I'm not relying on media. I am waiting for official reports. I tend to give people the benefit of the doubt. GZ said it was self defense, I believe that until something shows me otherwise. Yes it was unbelievably stupid for GZ to follow TM, but I don't see the underlying hatred of black people that some people think GZ has. I see a man who is concerned for his neighbors, their safety, and who seems to be a bit overzealous but not looking to kill.
People make dumb decisions every day, some are lethal: trying to make a yellow light and getting hit, starting their car to warm up in the garage and dying of carbon monoxide. But just as TM has every right to walk around that neighborhood so does GZ. IMO it comes down to who physically attacked who first.
