I guess Zimmerman was supposed to have waited until Martin beat him to death or brain damage before he was justified in defending himself. If only he had allowed his skull to be bashed in a little bit more, he would have a case. /sarc
Martin wasn’t bashing Zimmerman’s head with a chunk of concrete. He was bashing the chunk of concrete with Zimmerman’s head.
You rightly add the sarc tag but that is precisely what fat boy Bekel of The Five believes...and worse, the other four don't correct the idiot! A "normal" person would realize he was in a life threatening situation the instant some maniac sat on top of him and started bashing in his head.
