Where differences among circuits call for different instructions, alternatives are provided. The instructions are arranged using section 1962 (c) -- which prohibits racketeering in interstate or foreign commerce -- as the framework for analysis. Instructions for section 1962 (b), section 1962 (a), section 1962 (d), forfeiture, and section 1964 (c) are provided as well, however the case law for these sections, especially in the area of forfeiture, is not yet well developed. The instructions do not include a specific scienter requirement, but indicate where such requirements should be inserted by the court. In all RICO cases, judges and lawyers need to draft instructions based on the case at hand, explaining its particular issues to the jury.
