Its entirely possible. I think things stayed relatively calm after the Zimmerman verdict. But in Ferguson, I watched the news and saw more white kids than black kids. I saw white "anarchist" types running around. There were plenty of outsiders there this time, I have no doubt that they WANTED a riot for their own purposes.
With all the talking heads blathering on about Michael Brown and his family (some “family”, NOT!) what was upsetting to me was that only one person (Rudy Giuliani) bothered to mention Office Wilson, what emotions he was feeling before and after the announcement that he was not to be charged, and what this has done to him as a person and to his career. I have no idea what it must have been like for Officer Wilson to have to shoot Brown but believe it will haunt him for years to come. (I know a police officer that had to shoot someone in self defense who was trying to kill him. That incident caused him enormous emotional problems and he is still not over it.)
Unfortunately few people will be able to follow what has happened to Officer Wilson but I will pray for him as he continues to “fight for his life”. God Speed Officer Wilson.
