It doesn't take much. I lived thru Detroit back in the 60's, the Chicago riots during the Democratic Convention in 1968, and most recently we saw how a bunch of overpaid but still upset government workers acted in Madison, WI. We saw how crazy the town hall meetings got before the vote on ObamaCare, on the very verge of something bad happening. There's more than enough bitter acrimony between the fringe political factions in this country for something like that to happen.

Unrest can spread very, very quickly. We're seeing it in London right now, all over an unconfirmed report that the police shot a young man.

You're right...all it takes is a trigger.
