I took part in the Occupy protests in my town and what I saw is that it's usually just a few idiots who start the mindless destruction and a few more who follow suit. Unfortunately it's hard to tell who did what and so everyone who was protesting gets slapped with the label of rioter. We had some arrests here over the Ferguson decision last night in fact.
Also, Missouri is a deeply racially divided area compared to a lot of the country, it's not surprising that tensions are flaring.
Everybody good, plenty of slaves for my robot colony?
