QUESTION PRESENTED In order to warrant a two-level enhancement for possession of a firearm, pursuant to U.S.S.G. § 2D1.1(b)(1), is it sufficient to simply label firearms as “tools of the trade” which allows for an inference of possession when possessed by a co-defendant, as is the rule in the Fifth Circuit, or must there be reasonable foreseeability as required by the Sixth, Eight, Ninth, Eleventh and D.C. Circuits? 2
