All this would never happened if Zimmerman had just called the Cops and not followed Martin. What is what most block watch members are told to do.
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?
