From what I saw on the TV, there was nothing in common. What I saw was pure mob mentality destruction with no rhyme or reason behind it. For all intents and purposes, this could have been a scene in either Somalia or Rwanda.
I have seen this time and time again but in most of the cases it was described as "over exuberant fans" celebrating whatever........
FWIW, the 68 riots here in Detroit started out the same way........
I agree totally about the mob mentality and was implying no sympathy for the looters/vandals whatsoever. I was speaking generally about the common link between neo-nazis and neo-communists.
