I agree with all . Zimmerman says on the tape the guy is up to no good, he might be on drugs, he is criminally motivated by looking at houses, he is reaching for a weapon in his waistband. This was a highly dangerous person to follow and ask questions to and Zimmerman by his own choice wants a piece of this action. No sane person would follow a person on drugs, who he thinks has a weapon unless he wants something bad to happen.
