I dunno - I'm getting really bad flashbacks to the "Chief Thunder" case. That was the guy who made a sweetheart deal (ATF said "bribe") with some podunk PD to get them to sign LE sample letters, to import machine guns. When he was busted, he had ~150 full auto rifles sitting in a warehouse. He went away for a couple of years to Club Fed based on that. Call me paranoid, but the only way I'd play this game if I had strong assurances from legal authorities I trusted (somebody like Eugene Volokh or Chuck Michel, for example) that the whole scheme was legit.
