Cosby lost a son to a gun, give him a break. His comments are valid. Why did Zimmerman leave his vehicle? Why run into a non lethal situation? As Cosby stated in the past, the gun gave him the attitude. What was his training? I am a CC user in Orlando with force on force, advanced conceal and low light LEO training. Your first obligation is to avoid situations that can escalate. I don't know what happened, no one will. But someone died because a situation that could have been avoided. Zimmerman wouldn't be living in fear, and a man wouldn't be dead if he had walked away.
