The sad thing is that you have a small group of idiots who are going to get all of the attention for looting and perpetuating the stereotype, while there are thousands of people who are rightfully angry and scared and sad because it's all too obvious that those in authority aren't actually out to "serve and protect" them.
I mean, let's be honest--there are sports fans who riot when their teams win or lose games. There is always a group of idiots among any kind of a mob of people, and this mob has a whole lot of anger fueling it.
Really interesting stats on traffic stops/arrests/etc from MO's website. There is a massive discrepancy in black arrests vs. arrests of white (or really any other minority) arrests.

But rather than focusing on the justifiable outrage of the peaceful protesters, the focus will be on the destruction caused by these few idiots.
