1) Flash mobs to rob stores in broad daylight -- CHECK!
2) "Leaderless" urban occupation movements in multiple cities -- CHECK!
3) Widespread disruptive arson attacks over a broad area -- CHECK!
4) Random killings of people in a designated area over a period of weeks -- IN PROGRESS
The last is pure speculation on my part, but the Left has got property theft, social disruption, and property damage down pat by now. The only thing I'm not seeing is "random" loss of life. I think we'll see that in 2012.
Has already happened. Remember the "Beltway Snipers" in the Washington D.C. area?
You're correct.
I think we'll see this sort business again in the future.
