DISTRICT OF NEVADA Mack Miller, Case No. 2:23-cv-00070-CDS-DJA

Plaintiff Order Granting in Part the Defendant’s Motion for Summary Judgment and v. Granting the Defendants’ Partial Summary Judgment Clark County, et al.,

Defendants [ECF Nos. 61, 64]

Plaintiff Mack Miller brings this § 1983 suit against defendant Clark County and Preventative Measures Security Firm LLC, alleging personal injury arising out of a Clark County Board of County Commissioners meeting where two security guards physically removed Miller from the meeting (the “incident”). See Compl., ECF No. 2-2. On January 12, 2023, Preventive Measures removed this action from the Eighth Judicial District Court. See Pet., ECF No. 2. Thereafter, Miller amended his complaint, adding defendants Marco Solorio and Leonard Morris. Am. compl., ECF No. 17. On July 30, 2025, Clark County filed a motion for summary judgment. See Mot. for summ. j., ECF No. 61. This motion is fully briefed. See Resp., ECF No. 70; Reply, ECF No. 71. That same day, Preventive Measures, Solorio, and Morris (“the defendants”) filed a motion for partial summary judgment. See Mot. for partial summ. j., ECF Nos. 64, 65. This motion is also fully briefed. See Resp., ECF No. 69; Reply, ECF No. 72. For the reasons stated herein, I grant Clark County’s motion for summary judgment and the defendants’ partial summary judgment motion. I. Background1 and undisputed facts A. Summary of the events On September 21, 2021, Miller attended a Clark County Board of Commissioners meeting held at the Government Center’s Commission Chambers to consider “passing a resolution declaring COVID-19 misinformation a public health crisis.” ECF No. 17 at 3, ¶¶ 13, 16. During the meeting, a dispute broke out between meeting attendees and the defendants. Id. at ¶ 14. A Clark County Commissioner attempted to restore order to the hearing but was not successful, so the Commissioner ordered that the chambers to be cleared. See Elando Johnson dep., Def.’s Ex. F, ECF No. 61 at 35–36.2 In his complaint, Miller alleged that when he was exiting chambers, he observed a security guard shoving a female attendee, and when Miller asked the individual to identify himself, he was “rushed, shoved and attacked” by Solorio, Morris, and other Preventive Measures security guards. ECF No. 17 at ¶¶ 17–18. That guard was later identified as Clark County Security Guard (Cooperman), and Miller yelled and cursed at Cooperman. Meredith dep., Pl.’s Ex. 6, ECF No. 69 at 141;3 Millers dep., Pl.’s Ex. 1, ECF No. 69 at 18. Miller was then escorted out of chambers. Pl.’s Ex. 6, ECF No. 69 at 141. Miller alleges that when he was being physically lifted by Solorio, Morris, and other Preventive Measures guards, his back was shoved through the commission chambers double doors, through the hallway, and then ultimately through a metal detector that was in the hallway of the Commission chambers. Id. at ¶ 19. Miller alleges that he fell backwards into

1 Unless otherwise noted, the court only cites to the plaintiff’s amended complaint (ECF No. 17) to provide context to this action, not to indicate a finding of fact. 2 Clark County’s motion violates Local Rule IC 2-2(3), which requires exhibits and attachments “be attached as separate files,” not as part of the base document. Given the age of this case and the need for judicial efficiency, the court does not strike the filings under Local Rule IA 10-1(d). However, Clark County is cautioned that future violations of the rules may result in the court striking inappropriately filed documents or exhibits. Adherence to the rules assists the court in resolving motions more expeditiously. 3 Both of Miller’s responses to the summary judgment motions also violate Local Rule IC 2-2(3), which requires exhibits and attachments “be attached as separate files,” not as part of the base document. The same admonishment applies—future violations of the rules may result in the court striking inappropriately filed documents or exhibits. someone, and at some point, Solorio, Morris, and other Preventive Measures security guards knocked the metal detector into Miller’s head which caused him to lose consciousness and hit the back of his head on the floor. Id. at ¶ 22. The defendants contend that Miller was agitated and was acting “highly aggressive” in both behavior and language. Sutton dep., Defs.’ Ex. B, ECF No. 65 at 10; Def.’s Ex. J, ECF No. 61 at 77. Despite being ordered to leave, Miller did not comply; rather, he allegedly shoved Preventive Measures Operation Manager, David Sutton. Def.’s Ex. J, ECF No. 61 at 72. Sutton radioed for assistance in removing Miller and Officer Solorio grabbed Miller to take him outside. Id. Miller was carried out of chambers by Preventive Measures security guards through the subject metal detector, causing the metal detector to tip. Video, Def.’s Ex. D, ECF No. 61 at 00:36–0:39; Video, Def.’s Ex. C, ECF No. 61 at 00:00–0:03.4 However, Miller never appears to hit his head on the metal detector or floor, nor does he appear to trip over anyone. Def.’s Ex. C, ECF No. 61 at 00:00–0:05; Def.’s Ex. D, ECF No. 61 at 00:35–0:42. Prior to the metal detector tipping over, Clark County Officer Johnson can be seen removing a red board to clear the path for Miller to go through. See Def.’s Ex. C, ECF No. 61 at 00:00–0:06; Def.’s Ex. D, ECF No. 61 at 00:35–0:40. That same officer caught the metal detector as it was tipping and prevented it from falling on the floor and on Miller. See Def.’s Ex. C, ECF No. 61 at 00:00–0:06; Def.’s Ex. D, ECF No. 61 at 00:35– 0:45. Thereafter, Miller is slowly placed on the ground after going past the metal detector. See Def.’s Ex. C, ECF No. 61 at 00:05–0:10; Def.’s Ex. D, ECF No. 61 at 00:39–0:44.5
