Some of us are old enough to remember the riots that ensued after MLK Jr was assassinated.
Little Italy in downtown Baltimore was right across the street from some pretty serious projects. Not a dime of damage done,however.
Amazing what a few guys with guns on rooftops can accomplish.
I remember the July 13, 1977 New York Blackouts when their was widespread rioting and looting. The Lebanese Family that owned the local grocery store showed up with lawn chairs and long rifles. They sat around the store drinking tea and listening to that shitty Middle Eastern popular music on their boom boxes. Not a bit of trouble. And the da buthras really HATED the Lebanese.
