becoming more and more common, where large groups of youths run into stores, steal everything they can, in a short amount of time, and then leave.
yesterday, in chicago, a large mob of them run into a family owned store, and steal about 3000 dollars worth of jeans, beating employees who tried to stop them
I thought flash mobs were those dance groups who do these dancesin public areas without advertising them (like train stations, the street etc), but after some googling about this, this is turning into an epidemic apparently.
