I never indicated self-defense isn't a right. You are making that up. You are jumping to conclusions. You are putting words in my mouth. What I said was, when you allow someone to follow someone down the street and shoot them as they are running away because you think they might come back and shoot you when there was no indication they were armed, you are allowing them to get away with murder. Welcome to the Wild West. Just my opinion, just like your opinion is that I don't believe in self-defense. Oh wait, there's a difference. I actually showed cases where people were found not guilty or never even charged in really suspicious circumstances, because of the law. You just made a wild accusation based on "duh, gun grabbers think like this-".
Evidence doesn't always solve the case. In the Zimmerman case, the so-called eyewitnesses couldn't really see anything, could they? It was dark and they were too far away. They heard more than they saw and they couldn't really determine whose voice they were hearing.
We will never know all of the details of the killing of Trayvon Martin. However, we do know that Zimmerman was hunting, stalking him. He was told by the police to back off. The kid was on the phone with his friend and she said he was trying to shoo the guy off. Zimmerman was the aggressor. The kid had a right to defend himself, right? Gun "enthusiasts" seem to forget that part. I guess only the armed are allowed to defend themselves.
