For sure we don’t know the whole story. If things happened as you heard, then the officer may have been in fear for his life, but he still had options. Perhaps he thought he didn’t, I don’t know.
I don’t think what happened in Ferguson with Brown is the best example of police brutality. I think what happened in NY city and in Wanka’s home of Key West are better examples of police overstepping their bounds, but the trend appears to be one of police militarization to me. Some maybe justified and some not.
I stand by my statement that if it were a white kid, circumstances would be different. I blame Obama the race baiter for that. JMHO.
