They start out the same. People just begin gathering. One turns violent the other doesn’t.

If they look like gang-bangers, assume that that is what they are, and put distance between you and them.

The instant that a mob turns violent against any bystander, assume that you are in a situation of deadly danger.

I've watched several of the videos of flash mobs and not all but some looked like kids getting out of school or a movie, then the SHTF.

IMO, giving the impression of normalcy is part of the game. I know it is in the *knock out game*
