He did violate Neighborhood Watch protocol. Agreed. He did that by being Armed. Still, no law was broken. One should not testify to things they were not witness to, right. So, if you suspected a crime might be committed, would you get involved and act as an Eye Witness or walk/run the opposite direction? It's a fair question. There are a lot of different kinds of people out there. If you were attacked, how do you think Zimmerman would have reacted? Honestly? How do you think Martin would have reacted to you being in trouble? Which of the two do you think would have put Themselves at risk to help you?
Living, as I do, in a somewhat rough part of town, and having observed all kinds of people in my life, I would rather Martin came along if i was in trouble in the night, rather than someone like Zimmerman.
A long-time neighborhood watch dude in my part of the city was arrested a couple of years ago for raping a woman. Yes, that's right, the son of a bitch picked up a drunk woman and drove her to a warehouse he had a key to and raped her. He had worked in neighborhood watch for many years, was lauded by the cops, etc. etc.
Power corrupts.
Based on my experiences with black teenagers around my part of town, I'd trust them more. How many times have I seen them walking down the street and tensed up, only to have them flash me a big smile and say "Hello!"
Of course, even though I don't know them they may know me as the crazy woman who walks around with two Dobermans and a stun gun and bear spray hanging off her belt, and God knows what else in that fanny pack.
