Kelly might have made a better point if his record was at least a bit questionable.
Exactly. He should have first engaged in a massive crime spree, then in court smeared his own feces on his face and grabbed the gavel from the judge and pretended it was a pistol, pointing it at bailiffs and attorneys shouting "bang! Bang!" Then, after being committed and released from a psychiatric lock down, purchased a used gun that had already cleared the 20 day limit to demonstrate how easy it is.
Then he'd have had a point.
