Are you really comparing this to flash mobs? Do you even know what a flash mob is?

I know, I know!!

Gangs of black kids that rob stores or beat white people.

This is most definitely similar to a flash mob, but without the enjoyable staged dance number factor.

groups pick a time/location/victim

unobtrusively loiter or move to the appointed spot

execute the prearranged activity,

disperse and blend into the background....

There is a real rise in these types of attacks, on both coasts.

Stay alert

A flash mob used to be a “flash” gathering of people to do something entertaining or humorous. Planned in advance - be here at this time.

Nowdays a “flash mob” is a gang of yutes that quickly gather to trash a store or beat someone up. Tweeter or Facebook is used to quickly pass the word.
