He disrupted an event with intention to cause trouble (not engage in intelligent debate), he then shouted, swore, resisted arrest and struggled with four or five officers. He gave a play-by-play of his situation in the loudest voice he possibly could, obviously playing up to the cameras he saw on him. While he was so "painfully" tased for "doing nothing", he had the presense of mind to shout "OW! OW! OW! They're tasing me! OW! Stop!" etc. Honestly, it seems as though he was making as much of a fuss as he could with lousy acting all through something he brought upon himself. It's one thing to be politically active. It's another to be a gigantic billigerant moron in public.
I'm about as liberal as they come: but this kid was an asshat and deserved more than a tasing (he needs to be spanked by his mommy).
