@Tlalocelotl Not true.. he went to another state to help protect people and provide first aid. which he demonstrated by the fact that until he was assaulted by a mob he administered first aid to several people (including other protestors) and engaged in cleaning up graffitti.
So he went to another state to try to help people, provide aide, and provide protection. Which he did. He only killed someone who was trying to assault/kill him first and even went out of his way to avoid shooting back except as a last resort effort once he was cornered. Video tape clearly shows him making every effort to first run and scream "friendly friendly friendly" as the person chasing him were trying to knock him out by throwing things at him. He finally only shoots when the guy finally gets within arms reach to assault him physically.
How anyone can see the video and not see it as a very clear case of self defense and shooting only as a last resort is absolutely beyond me.
