WALLACE, Circuit Judge:
Following a bitter strike, unions representing employees of a Phelps Dodge Corporation facility (Phelps Dodge) and certain individuals (collectively the Steelworkers) sued Phelps Dodge, law enforcement officials and others for conspiracy to violate the civil rights of the Steelworkers. After dismissing some defendants, the district court granted summary judgment for Phelps Dodge, and judgment was entered pursuant to Fed.R.Civ.P. 54(b). The Steelworkers appealed, and a panel of this court affirmed. The appeal was subsequently taken en banc.
[1540]*1540The district court had jurisdiction pursuant to 28 U.S.C. § 1343, and we have jurisdiction under 28 U.S.C. § 1291. We reverse the judgment of the district court and remand the action for further proceedings. The opinion of the three-judge panel, reported at 833 F.2d 804 (9th Cir.1987), is withdrawn.
I
The background of this appeal was succinctly stated in the panel opinion:
Phelps Dodge owns and operates a copper mine and milling plant in Ajo, a few miles south of Tucson. In 1983, the unions representing those employees went on strike. By all accounts the strike was bitter, dividing the town and resulting in violence by both strikers and non-strikers. Huge demonstrations and violent confrontations met the company’s attempt to replace the strikers. In this explosive situation both Pima County Sheriffs Department Officers, and Arizona Public Safety Officers were called to Ajo.
During the strike, several strikers were arrested and charged with felonies. Bail was set at $15,000 for each. When they could not post bail they were jailed in nearby Tucson. Other strikers were arrested or cited and charged with misdemeanors.
The Steelworkers sued Phelps Dodge, Pima County, the Sheriff and individual Deputies, the Arizona Department of Public Safety and individual officers, individual attorneys of the County Attorney’s Office, and the Ajo Justice of the Peace for conspiracy to deprive the strikers and their supporters of their constitutional rights in violation of 42 U.S.C. § 1983. They alleged discriminatory enforcement of the law, arrests without probable cause, and excessive bail.
The State Department of Public Safety and its officers, the Justice of the Peace, and the attorneys were dismissed. The district court then granted summary judgment and costs for Phelps Dodge. The Steelworkers appealed, contending that sufficient evidence of a conspiracy was presented to require a jury trial.
United Steelworkers of America v. Phelps Dodge Corp., 833 F.2d 804, 805 (9th Cir.1987).
We review the entry of summary judgment independently. Darring v. Kincheloe, 783 F.2d 874, 876 (9th Cir.1986). We are governed by the same standard used by the trial court under Fed.R.Civ.P. 56(c). Id. Under that standard, summary judgment is appropriate only if “the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.” Fed.R.Civ.P. 56(e). Thus, the crucial question before us is whether the evidence presented by the Steelworkers, together with permissible inferences drawn from that evidence, is sufficient to establish a “genuine issue as to any material fact.”
II
The Steelworkers contend that a genuine issue exists as to whether Phelps Dodge was part of a conspiracy to deprive the strikers of their civil rights in violation of 42 U.S.C. § 1983. Actions may be brought pursuant to 42 U.S.C. § 1983 to redress constitutional violations under col- or of state law. Private parties act under color of state law if they willfully participate in joint action with state officials to deprive others of constitutional rights. Dennis v. Sparks, 449 U.S. 24, 27, 101 S.Ct. 183, 186, 66 L.Ed.2d 185 (1980); Adickes v. S.H. Kress & Co., 398 U.S. 144, 152, 90 S.Ct. 1598, 1605, 26 L.Ed.2d 142 (1970) (Adickes); United States v. Price, 383 U.S. 787, 794, 86 S.Ct. 1152, 1157, 16 L.Ed.2d 267 (1966); Fonda v. Gray, 707 F.2d 435, 437 (9th Cir.1983) {Fonda). Private parties involved in such a conspiracy may be liable under section 1983. Adickes, 398 U.S. at 152, 90 S.Ct. at 1605.
To prove a conspiracy between the state and private parties under section 1983, the Steelworkers must show “an agreement or ‘meeting of the minds’ to [1541]*1541violate constitutional rights.” Fonda, 707 F.2d at 438; see Adickes, 398 U.S. at 158, 90 S.Ct. at 1609. To be liable, each participant in the conspiracy need not know the exact details of the plan, but each participant must at least share the common objective of the conspiracy. Fonda, 707 F.2d at 438. Evidence that police failed to exercise independent judgment will support an inference of conspiracy with a private party. See Gramenos v. Jewel Companies, Inc., 797 F.2d 432, 435-36 (7th Cir.1986) (police agreement to arrest anyone designated by shopkeeper constitutes conspiracy), cert. denied, 481 U.S. 1028, 107 S.Ct. 1952, 95 L.Ed.2d 525 (1987); Moore v. Marketplace Restaurant, Inc., 754 F.2d 1336, 1352-53 (7th Cir.1985) (same).
Whether the Steelworkers have proven the existence of a conspiracy to deprive them of their civil rights is not before us. We assume for purposes of this appeal that such a conspiracy did exist and did violate their civil rights. We have before us only the narrow issue of whether the Steelworkers have alleged enough evidence that Phelps Dodge was in fact a participant in this conspiracy to defeat a motion for summary judgment. We first discuss the standard that the Steelworkers must satisfy to defeat a summary judgment motion. We then consider whether the Steelworkers have satisfied this standard.
A.
The Steelworkers rely primarily on Ad-ickes. The Court there concluded that unless the alleged conspirators foreclosed the possibility of a tacit agreement from which a conspiracy could be inferred, they were not entitled to summary judgment. 398 U.S. at 157, 90 S.Ct. at 1608. Adickes involved a white schoolteacher who was refused service in a public restaurant while in the company of several of her black students. As she left the restaurant, she was arrested for vagrancy by local police. Adickes brought a section 1983 claim against the restaurant, alleging that the refusal to serve her and her subsequent arrest were products of a conspiracy between a private individual (Kress) and a governmental entity (local police). The district court granted summary judgment against Adickes, ruling that she “failed to allege any facts from which a conspiracy might be inferred.” Adickes v. S.H. Kress & Co., 252 F.Supp. 140, 144 (S.D.N.Y.1966). The court of appeals affirmed. Adickes v. S.H. Kress & Co., 409 F.2d 121, 126-27 (2d Cir.1968).
The Supreme Court reversed, ruling that the alleged conspirators had failed to negate inferences that could be drawn from the presence of a policeman inside the restaurant while Adickes was awaiting service. Although the store manager’s deposition claimed that he had not seen or communicated with a policeman, there were no affidavits from two other employees present in the store at the time. Thus, Kress “did not carry its burden because of its failure to foreclose the possibility that there was a policeman in the Kress store while [Adickes] was awaiting service, and that this policeman reached an understanding with some Kress employee that [Adickes] not be served.” Adickes, 398 U.S, at 157, 90 S.Ct. at 1608. The Court held that there was circumstantial evidence of a conspiracy, and the “unexplained gaps” in the record were held against Kress because, as the moving party, it had the initial burden to show affirmative evidence of the nonexistence of a material fact in dispute. Id.
If the Supreme Court had given no further guidance, we would decide this appeal based on whether Phelps Dodge had foreclosed the possibility of the existence of facts from which an inference of conspiracy could be drawn. Phelps Dodge would have the burden of showing the absence of a genuine issue as to any material fact, and any unexplained gaps in the record would be held against it. Id. But the Supreme Court has given additional guidance in two subsequent decisions: Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986) (Liberty Lobby), and Celotex Corp. v. Catrett, 477 U.S. 317, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986) (Celotex).
In Liberty Lobby, the Court held that when a defendant moves for summary [1542]*1542judgment, the trial court must determine from the record whether “a fair-minded jury could return a verdict for the plaintiff on the evidence presented.” 477 U.S. at 252, 106 S.Ct. at 2512. The possibility that the plaintiff may discredit the defendant’s testimony at trial is not enough for the plaintiff to defeat a properly presented motion, “the plaintiff need only present [affirmative] evidence from which a jury might return a verdict in his favor.” Id. at 257, 106 S.Ct. at 2514. If from the evidence presented a jury could “reasonably find either that the plaintiff proved his case or that he did not,” id. at 254, 106 S.Ct. at 2513 (emphasis in original), summary judgment must be denied.
Liberty Lobby focuses the district court’s attention on the “actual quantum and quality of proof necessary to support liability” at trial. Id. Mere submission of affidavits opposing summary judgment is not enough; the court must consider whether the evidence presented in the affidavits is of sufficient caliber and quantity to support a jury verdict for the nonmovant. Id. A “scintilla of evidence,” or evidence that is “merely colorable” or “not significantly probative,” is not sufficient to present a genuine issue as to a material fact. Id. at 249-50, 252, 106 S.Ct. at 2510-11, 2512. The trial court, however, must keep in mind that “[credibility determinations, the weighing of the evidence, and the drawing of legitimate inferences from facts are jury functions, not those of a judge.... The evidence of the nonmovant is to be believed, and all justifiable inferences are to be drawn in his favor.” Id. at 255, 106 S.Ct. at 2513. A “justifiable inference” is not necessarily the most likely inference or the most persuasive inference. Rather, “an inference as to another material fact may be drawn in favor of the nonmoving party ... if it is ‘rational’ or ‘reasonable.’” T. W. Electrical Service v. Pacific Electrical Contractors, 809 F.2d 626, 631 (9th Cir.1987) (T.W. Electrical). Of course, the inference drawn must be one permitted under the governing substantive law. Id. This approach to evaluating a summary judgment motion is similar to the inquiry courts make to determine the appropriateness of a directed verdict pursuant to Fed.R.Civ.P. 50(a). Liberty Lobby, 477 U.S. at 250-52, 106 S.Ct. at 2511-12.
As a defamation action, the substantive law in Liberty Lobby required the plaintiff to prove certain elements of its ease with “elear-and-convincing evidence” — a heightened standard of proof. The approach announced by Liberty Lobby applies equally to “run-of-the-mill” civil cases which involve the preponderance-of-the-evidence standard. Id. at 252, 106 S.Ct. at 2512. Thus, Liberty Lobby’s focus on the sufficiency of the evidence at trial applies to summary judgment motions in all civil cases, and not just those which, like Liberty Lobby, involve the heightened “clear- and-convincing evidence” standard. Id. at 252-53, 106 S.Ct. at 2512-13; see, e.g., Canada v. Blain’s Helicopters, Inc., 831 F.2d 920, 922-23 (9th Cir.1987) (summary judgment appropriate if no reasonable juror could find for the plaintiff by a preponderance of the evidence (citing Liberty Lobby)). Indeed, the Court showed how conspiracy cases such as Adickes and First National Bank of Arizona v. Cities Service Co., 391 U.S. 253, 88 S.Ct. 1575, 20 L.Ed.2d 569 (1968), fall within the rule. Liberty Lobby, 477 U.S. at 249, 106 S.Ct. at 2510-11; see also T. W. Electrical, 809 F.2d at 630-31 (applying Liberty Lobby rule to summary judgment motion in conspiracy case).
Celotex was decided the same day as Liberty Lobby. Whereas Liberty Lobby focused on the quantum and quality of evidence required to withstand summary judgment, Celotex emphasized the allocation of burdens of proof. The Court held that on an issue where the plaintiff has the burden of proof, the defendant may move for summary judgment by pointing to the absence of facts to support the plaintiff’s claim. 477 U.S. at 322-23, 106 S.Ct. at 2552-53. The defendant is not required to produce evidence showing the absence of a genuine issue of material fact with respect to an issue where the plaintiff has the burden of proof. Id. at 325, 106 S.Ct. at 2554. Nor does Rule 56(c) require “that [1543]*1543the moving party support its motion with affidavits or other similar materials negating the nonmoving party’s claim.” Id. at 323, 106 S.Ct. at 2553 (emphasis in original).
In Celotex, the court of appeals had relied on Adickes to reverse the entry of summary judgment by the district court. The Court held that the Adickes language relied on by the court of appeals
should [not] be construed to mean that the burden is on the party moving for summary judgment to produce evidence showing the absence of a genuine issue of material fact, even with respect to an issue on which the nonmoving party bears the burden of proof. Instead, as we have explained, the burden on the moving party may be discharged by “showing” — that is, pointing out to the district court — that there is an absence of evidence to support the nonmoving party’s case.
Id. at 325, 106 S.Ct. at 2554.
Here, the burden of proof was on the Steelworkers to prove that Phelps Dodge was' a part of the conspiracy. Phelps Dodge, in moving for summary judgment, needed only point to shortfalls in the Steelworkers’ case to demonstrate the absence of evidence connecting it to the conspiracy. The Steelworkers concede that Phelps Dodge met this responsibility in moving for summary judgment. Unless the Steelworkers presented sufficient evidence to demonstrate that there was a triable issue of fact as to Phelps Dodge’s connection to the conspiracy, Phelps Dodge was entitled to summary judgment. We therefore must determine whether the Steelworkers presented “concrete evidence from which a reasonable jury could return a verdict in [their] favor.” Liberty Lobby, 477 U.S. at 256, 106 S.Ct. at 2514.
B.
The Steelworkers contend that their evidence is sufficient to raise a genuine issue as to Phelps Dodge’s connection to the conspiracy, and thus defeat Phelps Dodge’s summary judgment motion. Their argument rests on four principal lines of evidence: (1) Phelps Dodge’s powerful position in the small community of Ajo, and its close relationship with law enforcement officials involved in the strike; (2) the August 11, 1983, meeting between Phelps Dodge executives and various law enforcement officials, and the events which followed the meeting; (3) the unequal treatment by law enforcement officials of strikers and strikebreakers; and (4) active contact and cooperation between Phelps Dodge and law enforcement officials during the strike. We review the evidence in the light most favorable to the Steelworkers. Ashton v. Cory, 780 F.2d 816, 818 (9th Cir.1986).
1.
The Steelworkers point to many aspects of Phelps Dodge’s powerful position in the community of Ajo. Phelps Dodge is Ajo’s predominant employer. Phelps Dodge owns most of the property in Ajo, including virtually all available rental housing. Through Phelps Dodge Mercantile Company (Phelps Dodge Mercantile), Phelps Dodge also operates a company store.
Many individuals who played a role in breaking up the strike had significant ties to Phelps Dodge. The Ajo Justice of the Peace, who issued the arrest warrants in this case, was on furlough from her job as a Phelps Dodge security guard and could have returned to this job at any time with full seniority. She obtained her judicial position through a nomination by Phelps Dodge’s security chief. Her car bore the personalized license plates “PD AJO,” which stood for “Phelps Dodge Ajo.” Both Phelps Dodge and the Pima County Sheriff’s Department (Sheriff’s Department) employed her close relatives. She lived in housing rented from Phelps Dodge.
Numerous Sheriff’s Department deputies likewise lived in houses or apartments rented from Phelps Dodge. Spouses and relatives of several deputies worked for Phelps Dodge and some worked as strikebreakers during the strike. Several deputies were former Phelps Dodge employees.
[1544]*15442.
The Steelworkers rely most heavily on a meeting which took place on August 11, 1983, at Phelps Dodge, as described in the deposition of Deputy Pima County Attorney Casteel. Those present at the meeting included Casteel, Sheriff Dupnik and Lieutenant Garchow of the Sheriff’s Department, and Phelps Dodge’s Plant Manager, Labor Relations Manager, and Director of Security. Two days before the meeting, strikers for the first time had blocked the entrances to the Phelps Dodge plant gate and mine gate, preventing any shift change for a period of 36 hours. The police ordered the road closed. On the day before the meeting, there was a near-confrontation between strikers and a large contingent of Sheriff’s Department and Arizona Department of Public Safety officers. This incident led to negotiations between union leaders and Sheriff Dupnik resulting in a truce. Union leaders persuaded the strikers to disperse, and a shift change was permitted.
At the August 11 meeting, the Phelps Dodge representatives asked whether the police intended to take any action against the strikers who had damaged property and violated the law. Sheriff Dupnik responded that arrests would be made, although the police had not yet completed the list of those to be arrested, determined the charges, or secured the warrants. A Phelps Dodge representative asked about the bail for the strikers, and indicated that in view of the “circumstances” and “severity” of the charges, he hoped bond would be “set high.” He said that he “wanted those people off the streets.” At some point, Sheriff Dupnik said that he planned to request $15,000 bail for each striker. Sheriff Dupnik had a partial list of the strikers for whom he hoped to secure warrants. After the discussion of bail, Dupnik went over that list with the representatives of Phelps Dodge.
The Steelworkers argue that the meeting resulted in numerous irregularities that surrounded the arrests of certain strikers. They contend that in light of this meeting, the preparation of the warrants, the actual decision to arrest, and the setting of bail constitute important evidence which could support a finding of Phelps Dodge’s connection to the conspiracy. For example, after the meeting at Phelps Dodge, Casteel met with three Sheriff’s Department officers and, thereafter, she and two of these officers went to the office of the Justice of the Peace to obtain the warrants, based on complaints signed by a representative of the County Attorney. The justice made no probable cause determination, and received no sworn testimony from the officers. The warrants were nevertheless prepared, but held by the justice for two weeks, when she changed the date and then signed the warrants.
During the two weeks the justice held the warrants, there were no confrontations between strikers and police officers. Indeed, the police began reducing their forces, and the Pima County Attorney told the press that “we’d like to have things simmer down and not have to charge anyone with felonies” for the events of August 9.
Two days before the warrants were issued, Phelps Dodge lawyers and the Justice of the Peace entered the main Phelps Dodge office building within 20 minutes of each other. About an. hour and a half later, the justice and certain police officers left, followed shortly by the lawyers.
Sheriff Dupnik met with the Phelps Dodge Manager and Director of Security at Phelps Dodge on the date the arrest warrants were issued or the day before. Phelps Dodge acknowledges that the purpose of the meeting was to discuss the arrests of the strikers. The date the warrants were issued is the sole day for which Phelps Dodge could not produce its log of daily contacts between its security officers and the Sheriff’s Department.
The Justice of the Peace also followed unorthodox procedures in setting $15,000 bail for those arrested. She made no effort to individualize bail according to community ties, ownership of property in Ajo, ability to pay, likelihood of appearance, or whether an individual had turned himself in. Nor did she inquire, as she normally [1545]*1545would, whether the strength of the case against each individual warranted bail in that amount.
3.
The Steelworkers argue that evidence of different treatment by police of strikers and strikebreakers supports the inference of conspiracy between law enforcement officials and Phelps Dodge. The Steelworkers detail many examples of alleged disparity including inconsistent handling of telephone harassment claims, notably the furnishing of phone “grabbers” to trace calls made to strikebreakers but not to strikers; release on his own recognizance of a strikebreaker who committed an assault on a striker while burdensome bail was generally imposed on strikers; imposition of bail on strikers in excess of the maximum fine allowed for the misdemeanor charged; failure to investigate certain incidents involving use of guns by strikebreakers; failure to enforce traffic rules against strikebreakers; and failure to investigate and act on positive identification (by strikers) of strikebreakers engaged in public indecency and tire slashing.
4.
The Steelworkers also offered evidence of the close working relationship between Phelps Dodge and law enforcement personnel during the strike. These included regular radio contact between Phelps Dodge and other law enforcement personnel; sharing of intelligence; daily contact at the picket line area; and regular meetings. Phelps Dodge provided videotapes of strikers’ activities to assist in identifying lawbreakers. Sheriff Dupnik stated that his department had a “close working relationship” with Phelps Dodge security personnel. In fact, when the strike began, Phelps Dodge Mercantile established a charge account for the Sheriffs Department so that deputies on temporary assignment to Ajo during the strike could charge their meals at the company store.
The Steelworkers also produced evidence indicating that police relied on Phelps Dodge security personnel for instruction as to where the strikers should be allowed to picket. Police followed the Phelps Dodge Security Manager’s instructions not to enforce violations by strikebreakers of the stop sign outside the Phelps Dodge entrance. On the day that warrants to arrest strikers were issued, the police met with Phelps Dodge to discuss the arrests.
Ill
The evidence presented, in the light most favorable to the Steelworkers would, if believed by a jury, be sufficient to prove close relations between Phelps Dodge and the state actors. The question is whether the jury could properly infer from these concrete facts that Phelps Dodge was a co-conspirator.
A court evaluating a summary judgment motion must consider all “justifiable” and “legitimate” inferences in the nonmoving party’s favor. Matsushita Electric v. Zenith Radio, 475 U.S. 574, 587-88, 106 S.Ct. 1348, 1356, 89 L.Ed.2d 538 (1986) (Matsushita). Inferences may be drawn from underlying facts not in dispute such as background or contextual facts, as well as from disputed underlying facts which the judge must assume will be resolved at trial in favor of the nonmovant. T.W. Electrical, 809 F.2d at 631.
Phelps Dodge argues that it was confronted with a dangerous and potentially volatile situation requiring police protection. It contends that assisting the police in this protective effort is no violation of the Steelworkers’ civil rights. We agree. Indeed, citizens are properly urged to cooperate with law enforcement agencies when crime or civil disobedience is threatened. As we made clear in Arnold v. International Business Machines, 637 F.2d 1350 (9th Cir.1981), such cooperation does not prove conspiratorial conduct. There, the company cooperated with the police in investigating the possible theft of documents by an employee. Meetings between the company and representatives of law enforcement agencies, the district attorney, and the attorney general occurred. A cooperative investigation resulted. We affirmed the entry of summary judgment by [1546]*1546the district court of the employee’s action alleging a civil rights violation. We described the company’s involvement as follows:
It is undisputed that IBM had some involvement with the Task Force. The Task Force would not have existed but for IBM. IBM brought the information concerning possible criminal activity to the authorities. IBM turned over to the Task Force the information that it had gathered concerning the possible leaks of trade secrets during its own investigation. An IBM employee, Callahan, was a member of the Task Force. The Task Force relied heavily, perhaps exclusively, on IBM personnel in determining what information constituted trade secrets, and what documents were IBM documents. The district attorney relied on IBM attorneys to provide appropriate witnesses to testify before the grand jury. IBM supplied the Task Force with “buy money” to enable Bourget to purchase documents and information from the suspected thieves, while under surveillance. IBM also provided the Task Force with money for expenses incurred during the course of the investigation that could not be covered by the local budget. IBM also rented an airplane that was used by members of the Task Force for travel during the course of the investigation. It is clear that “but for” IBM’s involvement, there would have been no investigation, and Arnold never would have been arrested or indicted or had his residence searched.
Id. at 1357. There was no evidence in Arnold “that would tend to show that [the company] had some control or power over the Task Force, [or] that [the company] directed the Task Force to take action against Arnold_” Id. at 1356. Yet, we concluded, summary judgment was proper.
Here, too, there is abundant evidence of cooperative involvement between Phelps Dodge and law enforcement agencies. The question is, is there more? We believe there is. Here, the conspiracy is admitted for purposes of this appeal. This conspiracy is the “smoking gun.” The issue is whether the Steelworkers presented enough evidence for a reasonable jury to decide that Phelps Dodge helped pull the trigger.
At the August 11 meeting, Phelps Dodge did not merely agree to cooperate in an investigation. It did not merely provide the police with useful information. It did not merely ask that its gates be opened and its property and workers be protected. If that were all Phelps Dodge requested, this case would be like Arnold. Phelps Dodge, in contrast, wanted the police to arrest strikers and “keep them off the streets.” A reasonable jury could infer that this was not a request to keep strikers off the street in front of the plant, but off “the streets ” —all streets. Keeping strikers off all streets goes beyond protection of workers and property. It reflects an intent to punish the strikers. Nor is this all. Phelps Dodge further suggested that the police keep the strikers off the streets by setting high bail. A reasonable jury could infer that this reflects an intent to punish the strikers. This evidence is sufficient to satisfy the standard of Liberty Lobby. It is not just a “scintilla of evidence” or evidence that is “merely colorable” or “not significantly probative.” Liberty Lobby, 477 U.S. at 249-50, 252, 106 S.Ct. at 2510-11, 2512. This evidence may be viewed as Phelps Dodge’s own confession of its intent. It is unusually probative. It is not evidence of a collateral matter, but goes to the most critical issue in the case: whether Phelps Dodge intended to violate the strikers’ civil rights. Moreover, this evidence takes on additional significance given that Phelps Dodge’s requests came to fruition several weeks after the meeting. Based on this direct evidence, a jury could infer that Phelps Dodge was a participant in the conspiracy. Thus, this evidence is of the “quantum and quality of proof necessary to support liability” at trial. Id. at 254, 106 S.Ct. at 2513.
This direct and highly probative evidence makes the inferences that can be drawn from the abundant circumstantial evidence all the more “justifiable” and “legitimate.” Matsushita, 475 U.S. at 587-88, 106 S.Ct. at 1356-57. Phelps Dodge’s powerful stat[1547]*1547ure in Ajo, combined with its repeated contacts with the police, provide “undisputed background or contextual facts,” T.W. Electrical, 809 F.2d at 631, from which the jury could legitimately draw inferences. The jury would be justified in inferring that Phelps Dodge had both the ability and the opportunity to conspire with the police. The ability and opportunity to conspire, while insufficient alone, constitute circumstantial evidence of actual participation in the conspiracy. See Adickes, 398 U.S. at 158, 90 S.Ct. at 1609. This circumstantial evidence does not stand alone, but rather serves to buttress the direct evidence and the permissible inferences arising from it.
The conduct of the Justice of the Peace in issuing warrants without probable cause immediately following the August 11 meeting might be capable of innocent interpretation. The peculiar timing and aberrant procedure surrounding the writing of the warrants, however, would support a justifiable inference of conspiracy. Moreover, the Justice of the Peace did not issue the warrants until after yet another meeting with Phelps Dodge attorneys at the Phelps Dodge plant. Although susceptible of innocent interpretation, this too would support a justifiable inference of conspiracy. The same may be said of the Justice of the Peace’s unusual decision to set uniform bail.
The inferences that can be drawn from actions of the Justice of the Peace are bolstered by Phelps Dodge’s viewing of the list of those Sheriff Dupnik planned to arrest, and its opportunity to offer its ideas on the composition of the list before the arrests occurred. This alone does not constitute sufficient evidence of conspiracy to defeat Phelps Dodge’s summary judgment motion. Police may show a list of possible arrestees to a victim or witness for many innocent purposes. But an act done for a legitimate purpose in furtherance of a conspiracy may, together with other evidence, be evidence of a conspiratorial purpose. Braverman v. United States, 317 U.S. 49, 53, 63 S.Ct. at 99, 101, 87 L.Ed. 23 (1942).
The demonstrated disparate treatment of strikers and strikebreakers standing alone would not be sufficient evidence of a conspiracy. However, when viewed together with the other evidence offered by the Steelworkers, such evidence could also support an inference of conspiracy between Phelps Dodge and the police. The same can be said of the frequent contact between Phelps Dodge and the police. The deference to Phelps Dodge on where to permit picketing indicates Phelps Dodge’s substantial influence on matters within police discretion.
The inferences that can be drawn from all of this direct and circumstantial evidence, taken together, are of sufficient “quantum and quality” to create a genuine issue of material fact, Liberty Lobby, 477 U.S. at 254, 106 S.Ct. at 2513: whether Phelps Dodge participated in the conspiracy. Phelps Dodge argues that all the facts are now presented and that there are no facts proving the conspiratorial connection. It is true that there was no specific admission by a representative of Phelps Dodge that Phelps Dodge was a conspirator. That evidence is seldom available. The disputed fact here will be proven, if it can be, by other direct and circumstantial evidence. See Adickes, 398 U.S. at 158, 90 S.Ct. at 1609; Hampton v. Hanrahan, 600 F.2d 600, 621 (7th Cir.1979), rev’d in part on other grounds 446 U.S. 754, 100 S.Ct. 1987, 64 L.Ed.2d 670 (1980); Crowe v. Lucas, 595 F.2d 985, 993 (5th Cir.1979). Here, the direct and circumstantial evidence were sufficient to require the fact finder to make a decision. Whether the Steelworkers will succeed in proving their case will need to await a trial. We hold only that they may try to do so.
REVERSED.
