How much weight should a jury give to evidence of a conspiracy?

The weight to be given evidence and the reasonable inferences to be drawn therefrom is the prerogative of the jury. On appeal the evidence and proper inferences must be viewed in a light most favorable to the Government. Glasser v. United States, 315 U.S. 60, 80, 62 S.Ct. 457, 86 L.Ed. 680 (1942). Likewise, we are mindful of the well-established rule of this circuit that once a conspiracy is shown to exist, only slight evidence is required to connect a defendant with the conspiracy. United States v. Westover, 511 F.2d 1154 (9th Cir. 1975), cert. denied, 422 U.S. 1009, 95 S.Ct. 2633, 45 L.Ed.2d 673 (1975).
