knowing that a sentence of death was a possible penalty, he cannot have knowingly waived his constitutional right to remain silent. See Miranda v. Arizona, 384 U.S. 436, 86 S.Ct. 1602, 16 L.Ed.2d 694 (1966).
The same kind of argument was raised in United States v. Hall, 396 F.2d 841 (4th Cir.), cert. denied, 393 U.S. 918, 89 S.Ct. 248, 2 L.Ed.2d 205 (1968). The court rejected the argument saying:
It is undisputed that at the time of arrest Agent Dowling did not inform Hall of the punishment he might receive if he were convicted of the robbery with which he was charged. Hall argues that without this knowledge he simply was not in a position to make the knowing and voluntary waiver contemplated by Miranda. Miranda, however, reflects the Supreme Court’s concern that an accused might, to his detriment, forfeit rights afforded him by the Constitution simply because he was not aware that he possessed such rights. We do not find in that decision any intimation that knowledge of the punishment for the crime with which he was charged is a prerequisite to a valid waiver of constitutional rights and we conclude that the validity of Hall’s waiver is not vitiated by the admitted absence of knowledge or information as to the possible punishment.
Id. at 845. We agree. A police interrogator must neither abuse a suspect, nor seek to obtain a statement by coercion or inducement, nor otherwise deprive him of Fifth or Sixth Amendment rights. As a safeguard against such improprieties, the Miranda warnings have been prescribed. But a police interrogator’s job is to gain as much information about the alleged crime as possible without violating constitutional rights, and it is not his duty to apprise a suspect of the possible punishment for the crime under investigation. The ultimate punishment to be meted out upon one convicted of a crime depends on the nature of the formal charges filed, which is often a function of prosecutorial discretion, the outcome of the trial, and the exercise of discretion by the sentencing judge. At the investigatory stage of the criminal justice process, it is quite proper for an investigating officer to decline to speculate on the possible ultimate result. Therefore we hold that the court did not err in denying the motion to suppress the confession.
Appellant’s third point is that the trial court erred in denying appellant’s novel and imaginative request to be allowed to drink two cases of beer in order to demonstrate to the court his state of intoxication when he confessed. He argues that the experiment should have been allowed because the result would have been relevant to the question of whether he was capable of intelligently and voluntarily waiving his constitutional rights.
The admissibility of a test or experiment lies within the discretion of the trial judge. Reid v. State, 68 Fla. 105, 66 So. 725 (1914); Hisler v. State, 52 Fla. 30, 42 So. 692 (1906). A court should admit evidence of scientific tests and experiments only if the reliability of the results are widely recognized and accepted among scientists. Rodriguez v. State, 327 So.2d 903 (Fla. 3d DCA), cert. denied, 336 So.2d 1184 (Fla.1976); Coppolino v. State, 223 So.2d 68 (Fla. 2d DCA 1968), appeal dismissed, 234 So.2d 120 (Fla.1969), cert. denied, 399 U.S. 927, 90 S.Ct. 2242, 26 L.Ed.2d 794 (1970); 3 S. Card, Jones on Evidence, § 15:9 (6th ed. 1972).
To allow the defendant to present himself to the court for observation after drinking two cases of beer would have had a very predictable result but would not, it seems to us, have risen to the dignity of an accepted scientific test or experiment. Appellant’s motion was supported only by his own testimony that he was so intoxicated that he was not aware of what he was doing. There was other testimony, however, that he was coherent and functioning normally at the time of his arrest. Therefore we conclude that the trial court did not abuse its discretion in denying the motion.
We come now to the propriety of the sentence of death. The trial judge found that the murder was committed in the commission of or flight after committing rape and kidnapping, an aggravating circum
