1. The "whole Ferguson thing" was about the lack of indictment of a police officer shooting an unarmed person. A lot of people did not buy the grand jury verdict, and they're not entirely in the wrong about that. The protesters certainly were not out there saying "boy, we're glad Michael Brown tried to kill a cop and we want more of that." You're simply making that up.
2. "NY cops murdered continued it"? What the hell does this even mean in regards to "continuing it"? The Garner incident apparently has gone down the memory hole, never to be seen again.
You seem to have a very strange idea of how these events have transpired and why.
Freedom of speech is not freedom from criticism.
If I lived in or around Ferguson I would be disturbed by the violence and wouldn't know what to do. We have seen some positive images come out of the protests such as the cop hugging the black youth. We don't know their motives or if they are cop haters who will never accept any facts, or if they are trying to unite against the violence and feel powerless in the process. I'll save judgement.
I just know if the cops negatively profile all the protestors and the entire community, and the community negatively profiles all the cops, then it's going to lead to serious long term issues in Ferguson. I really hope that is not the case.
