You need to read up on the case a little more. Zimmerman appears to have stalked this kid and shot him for no reason other than thinking he was in the wrong neighborhood. They have the kid's last phone call up to the moment of the attack that pretty much nails Zimmerman as a killer. How the neighborhood let that loser on the Watch is beyond me.
According to the tapes, Zimmerman called the police to come to the neighborhood because he spotted Martin who was acting suspiciously. Zimmerman mentioned that Martin was wearing a hoodie and had his hands in his waistband. Zimmerman opined that Martin had something he was hiding. The implication was that it could be a weapon. The police advised Zimmerman not to follow Martin and that they would meet with Zimmerman when they got there. Zimmerman agreed to meet with them and asked them to call him on his cell phone when they arrived.
It appears from the various tapes that there was some sort of altercation with both men wrestling on the ground. From reports that I have seen, Zimmerman is clearly the bigger man weighing 250 pounds to Martin's 140 pounds. It is clear from the tapes that someone is calling for help.
Based on this information, it is hard to see this as a premeditated murder. Zimmerman clearly acted out of bounds and should have followed the advice of the police and not confronted Martin. Until we know the details of what prompted the altercation, it is difficult to form any conclusive judgment on exactly how and why lethal force was used. It is a tragedy, but it is hard to classify it as a hate crime.
Why the anti-white hysteria?
It’s possible that it’s the case that Zimmerman is a murderer, and there is also a lot of Anti-White, Anti-Second Amendment Hysteria associated with the case.
