No sh*t, Sherlock.
Slamming a man’s head into the concrete while beating him the face form the mount position is a violent felony for which he was shot to death, and deservedly so.
The race zombies, of which you are one, seem to ignore the fact that Zimmerman shot the little thug in order to save his life.
Period, end of story.
Making up crap is all you are good at. Concrete, hell the boy would have been justified in killing zimmermen , under the florida law. He was in fear of his life because some dead beat was stalking him. He should have hit him in the head with a baseball bat. Then the kid without a record would be alive and the sorry dead beat 28 year with a criminal record would be on the slab.
