OPINION
ODOM, Judge.
Appellant was convicted for capital murder. The trial court assessed his punishment at death after the jury affirmatively answered the issues submitted to them at the punishment phase of the trial. Article 37.071, V.A.C.C.P.
The record reflects that the deceased returned from work to his home where he discovered appellant in the act of burglary and theft. Appellant seized a long-bladed hunting knife and stabbed his victim a total of twenty-seven times, fatally wounding him. Appellant then took the money from the deceased’s wallet and fled.
Appellant raises nineteen grounds of error. We have grouped these into six general areas and will dispose of them in the following order: (1) denials of requested jury instructions; (2) challenges to the jury selection process; (3) complaints to the admission of evidence; (4) challenges to the sufficiency of the evidence on particular points; (5) complaints of prosecutorial jury arguments; and (6) attacks on the constitutionality of Art. 37.071, V.A.C.C.P.
JURY INSTRUCTION ISSUES
Appellant contends the trial court erroneously refused, after a timely request, to submit a charge on circumstantial evidence with regard to the issue of whether there was a probability he would commit future acts of violence constituting a continuing threat to society. (Issue number two of Art. 37.071, supra.) He argues that there can be no direct evidence on this issue since it pertains to the probability of a future act occurring, and therefore, he was entitled to a circumstantial evidence charge on this issue.
This is a question of first impression, and one of difficult determination. Some light may be cast on the subject by examining the rule that has required such a charge, or dispensed with the requirement, in other situations.
Judge Graves writing in Stocks v. State, 147 Tex.Cr.R. 164, 179 S.W.2d 305, at 308, reviewed statements of the rule in earlier cases:
“We early said in the case of Beason v. State, 43 Tex.Cr.R. 442, 67 S.W. 96, 98, 69 L.R.A. 193: ‘The rule is this: That it is only necessary where the main fact, or as one case puts it, “where the gravamen of the offense,” or, as another case has it, “where the act of the crime,” rests solely upon circumstantial evidence, that then it becomes a case known as a case of circumstantial evidence requiring a charge upon that. In the Buntain case, [Buntain v. State], 15 Tex.App. 515, Judge White used the following language: “If a court were required to charge the law of circumstantial evidence in all cases where reliance was had upon circumstances to establish any particular fact, then, indeed, there would be but few, if any, cases in which such a charge would not be required; but such is not the rule. A charge upon circumstantial evidence is only required when the evidence of the main facts essential to guilt is purely and entirely circumstantial.” ’
“Again, in Hanks v. State, Tex.Cr.App., 56 S.W. 922, we have said that: ‘We are [250]*250aware of the rule, and we adhere to the same, that when the main fact constituting the gravamen of the offense is proved by direct testimony, and the intent merely with which the act was done is proven by circumstantial evidence, a charge on circumstantial evidence will not be absolutely necessary.’
“Again, if the intent alone is determined by circumstances, such would not render the case as one depending upon circumstantial evidence. Jones v. State, 34 Tex.Cr.R. 490, 492, 31 S.W. 664.” (Emphasis added.)
The rule does not require a circumstantial evidence charge simply because intent is only shown circumstantially,1 and this rule has been reaffirmed in recent cases. Green v. State, Tex.Cr.App., 533 S.W.2d 769; Davis v. State, 516 S.W.2d 157; Sloan v. State, 515 S.W.2d 913.
The rule, then, does not require a circumstantial evidence charge on every facet of the case that is only supported by circumstantial evidence. Of what significance is this observation in the present context?
First, issues at the punishment stage are not submitted to establish “the gravamen of the offense,” or “the act of the crime,” or “the main facts essential to guilt.” Guilt has already been established when this stage of the proceedings is reached. In this respect the issue on which a circumstantial evidence charge was sought in this case is even further outside the scope of the established rule than is the issue of intent. By analogy we may say the established rule does not require a circumstantial evidence charge on the issue.
Second, inasmuch as the established rule appears to strike a distinction between proof of the culpable act (a matter of objective historical fact) and proof of mens rea (a matter of psychological fact), and requires a circumstantial evidence charge only on circumstantial proof of the former,2 proof of the second issue of Art. 37.071, supra, by circumstantial evidence would not appear to require a circumstantial evidence charge, the issue being one of a psychological fact rather than objective historical fact. The judgment the jury is called upon to make in answering this issue is one that by its very nature may only be made upon consideration of numerous and various circumstances that are incapable of reduction to an exhaustive, comprehensive list. This very character of the issue led the United States Supreme Court in Jurek v. Texas, 428 U.S. 262, 96 S.Ct. 2950, 49 L.Ed.2d 929, to uphold the Texas statutory scheme because this issue so construed affords the defendant found guilty of capital murder the opportunity to present mitigating circumstances to the jury at the punishment stage. That Court further described this issue thusly:
“Focusing on the second statutory question that Texas requires a jury to answer in considering whether to impose a death sentence, the petitioner argues that it is impossible to predict future behavior and that the question is so vague as to be meaningless. It is, of course, not easy to predict future behavior. The fact that such a determination is difficult, however, does not mean that it cannot be made. Indeed, prediction of future criminal conduct is an essential element in many of the decisions rendered throughout our criminal justice system. The decision whether to admit a defendant to bail, for instance, must of[251]*251ten turn on a judge’s prediction of the defendant’s future conduct. And any sentencing authority must predict a convicted person’s probable future conduct when it engages in the process of determining what punishment to impose. For those sentenced to prison, these same predictions must be made by parole authorities. The task that a Texas jury must perform in answering the statutory question in issue is thus basically no different from the task performed countless times each day throughout the American system of criminal justice. What is essential is that the jury have before it all possible relevant information about the individual defendant whose fate it must determine. Texas law clearly assures that all such evidence will be adduced.” (Footnotes omitted.) 428 U.S., at 274, 96 S.Ct., at 2957.
For these reasons we conclude that issue number two of Art. 37.071, supra, is an issue that does not fall within the rule that dictates use of the circumstantial evidence charge. The ground of error is overruled.
Appellant also contends that the trial court improperly denied his request to instruct the jury at the punishment stage of the trial that one act of capital murder does not establish a pattern of behavior from which can be inferred a probability that the appellant would commit future criminal acts of violence constituting a continuing threat to society.
Such a charge would have constituted an improper comment on the weight of the evidence and was properly denied. This ground of error is also overruled.
JURY SELECTION ISSUES
Two grounds of error raise jury selection issues.
First, appellant contends that the prohibitions of Witherspoon v. Illinois, 391 U.S. 510, 88 S.Ct. 1770, 20 L.Ed.2d 776, were violated when the trial court sustained the State’s challenge for cause to prospective jurors J. C. Barton and Mrs. Jimmy L. Conner.
We overrule the contention regarding Barton because no objection was voiced to the exclusion of this prospective juror. Boulware v. State, Tex.Cr.App., 542 S.W.2d 677, at 683, states:
“. . .we hold that the failure to object to the improper exclusion of a ve-nire member waives that right and it cannot be considered on appeal.”
An exception to the exclusion for cause of Mrs. Conner was voiced. She, however, stated that she could not take the oath provided by V.T.C.A., Penal Code Sec. 12.-31(b).3
In Moore v. State, Tex.Cr.App., 542 S.W.2d 664, we held that the inability to take the oath required by this statute disqualifies the prospective juror and Wither-spoon considerations are unnecessary. Mrs. Conner was properly excused.
The second complaint of improper jury selection process alleges that the requirements of Art. 34.04, V.A.C.C.P.4 were vio[252]*252lated by the trial court. During the voir dire, the appellant notified the court that one of the veniremen had been called out of order. The trial court replied that one of the prospective jurors had been summoned but had established a reason that he deemed sufficient for her excuse pursuant to Art. 35.03, V.A.C.C.P.5 This excuse was given under oath.
Article 34.04, supra, was allegedly violated because the trial court denied appellant’s motion requesting a recess in the proceeding until the attendance of the excused venireman could be secured. It is also urged that error was committed by the trial court’s failure, after timely motion, to have the State exercise a peremptory challenge against the excused venireman. Finally, it is contended that the trial court should have granted the motion for mistrial entered at this stage in the jury selection process.
Initially, we observe that appellant has not challenged the sufficiency of the sworn excuse given by the prospective juror to the trial judge.
A violation of Art. 34.04, supra, is not presented by the record. Appellant never states that he was denied the procedure outlined by this statute. Rather, he asserts that its provisions have been violated because the trial court excused a juror for a reason given under oath as provided for in Art. 35.03, supra.
We perceive no error in the action of the trial court. The action requested was unnecessary and would have delayed the formulation of the jury. Article 34.04, supra. This ground of error is overruled.6
EVIDENTIARY ISSUES
Various complaints concerning the admission of certain exhibits and testimony have been raised by this appeal.
Objection was made to the introduction of eight exhibits by the State. These items were seized at the residence of Rebecca Casey Kubala and they connected appellant with the offense. Kubala executed a written consent to this search. It is argued, however, that Kubala’s consent to the search was involuntary and coerced because she was informed by the police that a search warrant would be obtained if she did not sign the consent form. We are also presented with the claims that Kubala was under duress because she was surrounded by an “army of police” and that the police began searching the apartment before she signed the consent form.
Kubala testified at the suppression hearing that her consent was given voluntarily and that no threats or promises had been made. She stated that she told the police they could search her apartment before she left the police station. In other words, oral consent to the search was given before she signed the consent form. Kubala also described the police as being “nice” to her.
The allegations of coercion and duress are not supported by the record. Ku-bala did state that she thought the police had a search warrant at the time she signed the consent form and that she was told the police would obtain a warrant if she did not consent to the search. This, however, does [253]*253not compel us to conclude that the consent was unlawfully obtained. Resendez v. State, Tex.Cr.App., 523 S.W.2d 700; Stephenson v. State, Tex.Cr.App., 494 S.W.2d 900.
Kubala’s consent to the search of her apartment was voluntary. The evidence seized was properly admitted. Swift v. State, Tex.Cr.App., 509 S.W.2d 586; Maldonado v. State, Tex.Cr.App., 397 S.W.2d 862.
Appellant insists that his confession was improperly admitted into evidence. He argues that the confession was obtained only after he was confronted with evidence illegally seized in the search of Kubala’s residence. These exhibits, under our holding above, were not seized unlawfully. The confession, therefore, was not “tainted” and was properly admitted into evidence. Morrison v. State, Tex.Cr.App., 508 S.W.2d 827.
We must determine whether error was committed by the admission into evidence of the knife used to kill the deceased: Appellant maintains that the weapon was recovered only after he was confronted with illegally seized evidence. The “illegally” seized evidence, once again, consists of those items discovered in Kubala’s apartment. The murder weapon was found as a result of the confession and it too was properly admitted into evidence.
The admission of two photographic exhibits of the deceased is challenged. It is urged that this evidence was cumulative, depicting the same evidence shown in two previously admitted photographic exhibits, and that its probative value was far outweighed by its inflammatory and prejudicial aspects.
Prior to the admission of the complained of evidence, the other exhibits were properly introduced into evidence. These photographs depicted a frontal view of the deceased. The deceased’s chest and abdomen areas were covered by a shirt in these pictures.
Later, Officer T. W. Jackson testified and identified two exhibits as being fair and accurate representations of the victim’s chest and facial features on the date of the offense. One is a close-up of the victim’s bare chest and abdomen. It shows the placement and number of stab wounds inflicted by the appellant. The other is a close-up of the deceased’s head. It shows a scalp wound.
Hence the record shows that these photographs are not cumulative. Neither are they unduly inflammatory and prejudicial. The trial court did not abuse its discretion. Harrington v. State, Tex.Cr.App., 547 S.W.2d 621 (1977); Fazzino v. State, Tex.Cr.App., 531 S.W.2d 818; Martin v. State, Tex.Cr.App., 475 S.W.2d 265. The admission of the complained of photographs was not error.
Finally, the admission of the testimony of Dr. Richard Gaines, a psychiatrist, during the punishment stage of the trial is contested. Dr. Gaines was called by the State to give his opinion on the probability of appellant committing criminal acts of violence in the future that would constitute a continuing threat to society. Article 37.071, V.A.C.C.P.
Appellant was originally indicted for capital murder in trial cause no. 23,026. During proceedings under this cause number, appellant’s counsel requested the court to appoint a psychiatrist to determine whether the appellant was sane or insane at the time the offense was committed and to ascertain if he was competent to stand trial. Article 46.02, V.A.C.C.P.7 The court granted this motion and ordered Dr. Gaines to conduct an examination of appellant.
Dr. Gaines examined the appellant, met with appellant’s counsel, and gathered personal and background information concerning the appellant. Dr. Gaines was also assisted by another person who administered psychological tests.
After the examination, interviews and testing, Dr. Gaines met with appellant and his counsel. Appellant concluded that Dr. Gaines would not be called as a witness by the defense.
[254]*254Subsequent to the appointment of the psychiatrist, the appellant’s motion to quash the indictment in cause no. 23,026 was granted. Appellant was then reindicted for capital murder in trial cause no. 23,781, and his present appeal comes from the conviction obtained thereon. No psychiatric examinations were conducted during the proceedings held under the new cause number.
Dr. Gaines was subpoenaed by the State to testify during the punishment stage of the trial. His testimony concerning appellant’s propensity to commit future acts of violence was adverse to the defense. Dr. Gaines also testified that he could not have reached his opinions and conclusions with regard to the appellant’s propensity to commit future acts of violence if the appellant and his counsel had not provided him with information.
Appellant contends the admission of Dr. Gaines’ testimony violated: his Fifth Amendment right against self-incrimination; his Sixth Amendment right to effective counsel; the attorney-client privilege and the “work product” doctrine; Articles 46.02(3)(f), 39.14, and 28.05, V.A.C.C.P.; and the Equal Protection Clause of the Fourteenth Amendment. We shall consider each of these allegations.
Appellant’s right against self-incrimination guaranteed by the Texas and Federal Constitutions was not violated. Livingston v. State, Tex.Cr.App., 542 S.W.2d 655. There is nothing in the record to establish that this witness “revealed any fact or communication between him and the appellant showing that appellant committed a crime of any nature.” Granviel v. State, Tex.Cr.App., 552 S.W.2d 107 (1976).
Appellant argues that his right to effective assistance of counsel demands that expert psychiatric assistance be made available to his counsel in order to assure that every possible means of defense will be explored. In other words, defense counsel must be provided psychiatric assistance in order to ascertain if he was insane at the time the offense was committed.
According to appellant, this psychiatrist should not be allowed to testify in a manner adverse to the accused at the punishment stage of the trial. To allow the psychiatrist to enter adverse testimony would render counsel ineffective because such evidence was gathered at the behest of the accused’s attorney. In short, the counsel’s effective representation in seeking psychiatric evidence in order to determine the accused’s sanity would later be rendered ineffective by the physician’s adverse testimony on punishment.
Accepting appellant’s position on this issue would amount to a retreat from our decisions in Granviel v. State, supra; Moore v. State, supra; Livingston v. State, supra; and Gholson v. State, Tex.Cr.App., 542 S.W.2d 395. This we decline to do. Also see, Stultz v. State, Tex.Cr.App., 500 S.W.2d 853.
Appellant has not been denied effective assistance of counsel.
Appellant also contends that the attorney-client privilege and the “work product” doctrine were violated when Dr. Gaines testified at the punishment stage of the trial. Article 46.02, supra, provides that a psychiatrist can be appointed to examine a defendant on the motion of the court, the defense counsel or the prosecutor. The psychiatrist so appointed is a disinterested witness; his examination, conclusions, and opinions do not constitute the “work product” of the State or the defense and either party may subpoena this physician. Granviel v. State, supra.
Likewise, Article 46.02(3)(f), supra, has not been violated by the introduction of testimony from Dr. Gaines. This statute provides that the statements made by an accused during the examination or hearing on his competency to stand trial may not be admitted against him on the issue of guilt. Dr. Gaines’ testimony was admitted at the punishment stage of the trial, and, furthermore, none of appellant’s statements were introduced into evidence. Granviel v. State, supra.
Appellant’s claim in regard to Art. 39.14, supra, has no validity. This statute con[255]*255cerns discovery of material in the possession of the State.
Article 28.05, supra, governs procedure after a felony indictment is quashed. It reads:
“If the motion to set aside or the exception to the indictment in cases of felony be sustained, the defendant shall not therefore be discharged, but may immediately be recommitted by order of the court, upon motion of the State’s attorney or without motion; and proceedings may afterward be had against him as if no prosecution had ever been commenced.”
Appellant argues that this statute renders Dr. Gaines’ testimony invalid for all purposes because the psychiatric examination was conducted prior to the sustaining of the motion to quash the indictment in trial cause no. 23,026. His theory is that Dr. Gaines’ opinions were formulated in the prior cause no. 23,026, and cannot be used in this case, no. 23,781, because the new cause must proceed “as if no prosecution had ever been commenced.” Article 28.05, supra.
This is a novel, but unpersuasive theory. Article 28.05, supra, does not control what evidence may be presented at the punishment stage of a capital murder trial. See, Art. 37.071, supra. We overrule this contention.
The final argument asserts violation of the Equal Protection Clause of the Fourteenth Amendment. Appellant argues that he, as an indigent defendant, does not have the funds to retain a private psychiatrist to examine him for purposes of a competency determination. If he had such funds, he could employ physicians to examine him and he would not have to disclose their names to the State. In this manner, the State would not be able to ascertain the name of a psychiatrist that it could later subpoena to testify against the appellant at the punishment stage of the trial.
Article 46.02, supra, outlines a procedure to be followed when a question concerning the accused’s competency to stand trial is raised. Appellant’s argument does not negate the fact that Art. 46.02, supra, may be utilized whether the accused is wealthy or poor. The State may request or the court on its own motion may order a psychiatrist to examine the accused. This psychiatrist may later testify pursuant to Art. 37.071, supra, at the punishment stage of the trial, if his testimony is relevant. It should be noted that the physician’s testimony can also be advantageous to the accused. See Robinson v. State, Tex.Cr.App., 548 S.W.2d 63 (1977).
Furthermore, if the State discovers the rich defendant’s psychiatrists, they may be subpoenaed to testify at the punishment stage of the trial because Texas does not recognize a doctor-patient evidentiary privilege. Granviel v. State, supra.
We perceive no violation of the Equal Protection Clause of the Fourteenth Amendment. It was not error to admit Dr. Gaines’ testimony.
SUFFICIENCY OF THE EVIDENCE ISSUES
Appellant raises two grounds of error regarding the sufficiency of the evidence, one directed to proof of an element of the offense, and the other directed to proof of one of the punishment issues.
Challenge is raised to the sufficiency of the evidence to show this murder was committed in the course of robbery as alleged in the indictment under V.T.C.A., Penal Code Sec. 19.03(a)(2).
Appellant’s confession shows burglary of the deceased’s home followed by theft of numerous items including coins of the United States. The deceased then arrived and appellant stabbed him to death. He then removed the deceased’s wallet and stole the money in it.
V.T.C.A., Penal Code Sec. 29.02 defines robbery in part as follows:
“A person commits an offense if, in the course of committing theft as defined in Chapter 31 of this code and with intent to obtain or maintain control of the property, he:
[256]*256“(1) intentionally, knowingly, or recklessly causes bodily injury to another; . ” (Emphasis added.)
Appellant’s attack appears to be centered on the emphasized language. The indictment alleged the property to be “good and lawful U.S. Currency.” Appellant asserts (1) the coins taken before the killing are not currency and (2) at the time of the killing there was no intent “to obtain or maintain control of the property” taken from deceased’s wallet. By its own terms, appellant’s two-pronged attack is viable only if both assertions are valid.
In Casias v. State, Tex.Cr.App., 452 S.W.2d 483, it was held that coins are currency. Accordingly, the first prong of appellant’s attack is not valid, and the ground of error is without merit.
Another ground of error challenges the sufficiency of the evidence to prove that there is a probability appellant will commit criminal acts of violence constituting a continuing threat to society. Article 37.071, supra. We do not agree.
At the punishment stage of the trial, the State elicited evidence from Officer Vernon McKenzie and Chief Leonard Hancock of the Temple Police Department and Dr. Richard Gaines. The two policemen testified that the appellant’s reputation in the community for being a peaceable and law-abiding citizen was bad.
Dr. Gaines testified that the appellant had a potential for committing criminal acts of violence and that he would be more likely than the average person to engage in acts of violence in society. The doctor also stated that the appellant would be a multiple number of times more likely than the average person to engage in future acts of violence.
The doctor did, however, testify that he could not state that there was a “reasonable medical probability” that the appellant would commit future acts of violence.
The jury was also permitted to consider all of the evidence presented at the guilt stage, including appellant’s confession admitting the offenses of theft of a motor vehicle, burglary of a habitation, theft of personal property, and aggravated robbery. This evidence also established that the appellant stabbed the deceased twenty-seven times with a hunting knife.
The testimony of the two police officers and Dr. Gaines when coupled with the rest of the evidence presented at trial is sufficient to support the jury’s conclusion that there was a probability appellant would commit future acts of violence constituting a continuing threat to society. We overrule the ground of error.
JURY ARGUMENT ISSUES
Three grounds of error complain of jury arguments by the prosecutor.
It is first asserted that the trial court should have declared a mistrial after the prosecutor, during jury argument, stated that it was a reasonable deduction from the evidence that: “The lust for blood is what overcame John Charles Shippy.”
The trial court sustained appellant’s objection and promptly instructed the jury to disregard the statement. A motion for mistrial was denied.
The court’s action cured any harm caused by the argument. Curtis v. State, Tex.Cr.App., 519 S.W.2d 883; Pringle v. State, Tex.Cr.App., 511 S.W.2d 35. We overrule this ground of error.
It is also contended that the prosecutor misstated the law in his jury argument during the punishment stage of the trial, and that the argument was prejudicial and calculated to mislead the jury.
The complained of statements consist of two segments of the jury argument:
“What we are really talking about in this stage of the trial, ladies and gentlemen, is deterence. We need to have de-terence. You know what I mean by de-terence. That means if you punish one man for a crime maybe someone else down the line who has it in his head to commit the same kind of crime might stop and think. I mean, he may be thinking about going into this house over here [257]*257and he says, well, I can probably rip off some property pretty easily, probably steal some stuff, you know, and give (sic) me some money, but wait a minute, John Charles Shippy did that and he killed a man in the process.”
“Why else would he stab the man to death unless it is just that he didn’t want to leave a witness. If we don’t stop people who do that they will never leave a witness, I mean, you have got a chance of getting caught if there is a witness there, but if you leave that witness dead there is much less chance of your getting caught. Only this time due to excellent police work and citizen participation this man was caught, and we have got to deter other people who might commit burglary, robberies, whatever crimes, and decide that they will kill their witness so they won’t leave anyone to point their finger at them.”
We perceive no misstatement of law in this argument. The prosecutor’s statements amount to a plea for law enforcement and they are not improper. Alejandro v. State, Tex.Cr.App., 493 S.W.2d 230. We also observe that this argument was not outside the record. Appellant’s confession and other evidence established that he committed the crimes of burglary, robbery and murder on the night of the offense. This ground of error is overruled.
Finally, appellant asserts his motion for mistrial should have been granted when the prosecutor argued at the punishment stage of the trial:
“I can’t help but wonder what Dr. Gaines might have said about John Charles Shippy on April 16, 1975, if he had seen him. We can presume since it was based on some analysis and visiting with him very possibly he would have said the man is possibly a violent person, that he is a multitude times greater risk than the ordinary person. Might have been the same, but would he have probably committed criminal acts of violence. He did. He sure did. What would the opinion have been on that date, the day before this atrocity was committed.”
Objection to this argument was sustained and the jury was instructed to disregard the statements. We conclude that the court’s action cured the effect of these improper statements. Curtis v. State, supra; Pringle v. State, supra. The ground of error is overruled.
CONSTITUTIONALITY OF ART. 37.071, V.A.C.C.P.
Appellant’s last five grounds of error attack the constitutionality of Art. 37.071, V.A.C.C.P. on various grounds. These have previously been considered by this Court, and the constitutional validity of the statute has been pronounced by the United States Supreme Court in Jurek v. Texas, supra. The grounds of error are overruled.
The judgment is affirmed.
