This is an actual argument made on this forum. Because if we can't prove legality to a trumper it must have been illegality. Nevermind the fact that it's the trumpers responsibility to back up his accusation of illegality, which of course he doesn't. But he doesn't have to because you can't prove you didn't cheat. Apparently not innocent until proven guilty, but precisely the opposite - guilty until proven innocent.
What a crock. There as a time where both sides would have laughed this nonsense up out the forum. Guilty until proven innocent was universally shunned here.
