After waiver of a jury trial, appellant was convicted by the court of violation of 21 U.S.C. § 844 [possession of heroin]. He appeals from the judgment of conviction and sentence. We affirm.
ISSUE
The sole issue before us is whether the trial judge committed error in failing to receive beneficial polygraphic 1 evidence offered by appellant.
ANALYSIS AND CONCLUSION
In support of his contention, appellant directs our attention to volume after volume of testimony, produced at the preliminary hearing, pointing to the reliability of this type evidence. During the four day hearing, the appellant called a substantial number of experts qualified in the field of polygraphy and in the related fields of psychology, psychiatry and physiology. Simply stated, the evidence at the hearing vigorously supports the accuracy of polygraphic evidence. In the trial on the merits, the testimony of appellant was in direct conflict with that of the officers on the principal issues.
Despite the strong showing made by appellant, we are not ready to say that the trial judge abused his discretion in rejecting the offer. United States v. Salazar-Gaeta,
Moreover, our analysis of the record convinces us that the trial judge did not believe appellant in those instances where his testimony conflicted with that of the government witnesses. In these circumstances the error, if any, in rejecting the evidence would be harmless under Rule 52(a), FRCrimP. We do not hold that polygraphic evidence is never admissible.
Judgment affirmed.
