What "professional"? He doesn't have any education nor any professional experience, he has never been employed by any serious and respectable employer. He is a convicted criminal. So what kind of a professional do you expect him to be? He can't even be considered a professional criminal. He is just a dumb animal of homo sapiens spieces, one of billions, that's all he is, no "professional". Getting himself to a federal prison by selling explosives on eBay can really achieve only a total moron.
