I thought Trayvon Martin was killed because of self-defense by George Zimmerman while being beaten on the sidewalk. Are they suggesting that self-defense laws be eliminated?
According to what Zimmerman has said, Martin was trying to get his gun. So it wasn't just the danger of being knocked unconscious by repeatedly having his head hit against the concrete sidewalk, but a real danger of being shot dead with his own gun.
But Zimmerman is guilty for walking around his neighborhood rather than staying in his vehicle. Or for not being at the movie theatre. Or whatever.
