What is the effect of a prosecutor's statement to the jury that the sexual assault charge was within permissible limits?

The charge was certainly within the permissible limits set by United States v. Mont, 306 F.2d 412 (2d Cir.), cert. denied, 371 U.S. 935, 83 S.Ct. 310, 9 L.Ed. 2d 272 (1962) and United States v. Evans, 312 F.2d 556 (2d Cir. 1963), and is, in the absence of exception, controlling here. This conclusion is not altered by the incorrect statements of government counsel made to the jury, without objection, in his attempt to explain the effect of the statutory presumption. The judge was careful to point out that the burden of proof always remained with the government and taken in the context of the entire trial and charge the prosecutor's remarks do not require reversal.
