i had the same experience except it was 3 brown fellas who decided to throw a BIG rock (softball size) at a (white) mentally-ill bum under a tree who didn't talk to anyone much less look at anyone because if they saw his eyes they'd know he was f'in crazy. (missed my head by a couple of feet). Then they said "lets throw him in the river" and they might have until the bum defended himself. Dirty racist USA.
