You've got this troll pegged rightly, but I do enjoy seeing him and his deceit ridiculed. If you apply the 'devil's advocate' theory, he is trying to make the drugwarrior seem as stupid and fascist as possible, thereby trying to stereotype the drugwarrior as such, and desiring this jackbooted stereotype be generally accepted. Why? He's most likely a pusher himself. He doesn't want pot or coke or horse or anything like that legal because he enjoys his income.
I think you're right. His "documents" are always too easily shown to be bogus. He, like all drug pushers, supports the War on Drugs to protect his profits.
I really don't care why he's doing it, there isn't any excuse for it.
