Dan, I would like to offer this up to you if you will take a minute to read it.

Everyone MUST understand that those that comprise the flashmobs are not afraid of jail, police, momma, or armed citizens. Revenge is their lexicon...
OK, I read it and also read that none of the victims offered any credible resistance. I have dealt with a mob on 2 different occasions in my life and neither time did the punks have any stomach for the surrender of their life. At the moment, these mobs exist because the police and the courts offer no threat to them.
