I'm almost in total agreement with you.
I prefer not to enter areas where I feel the need for a gun. Been pretty successful at it.
It’s a dirty trick to willingly engage in a fight knowing you can kill the other guy if he gets the best of you if you are on neutral ground. It’s not a war situation.
"I" believe Trayvon attacked Zimmerman so he got himself shot. But Zimmerman had put himself in a situation where he might have to use his gun, so Zimmerman was responsible for Travon's death. He had no business being armed in the capacity of a neighborhood watchman.
