When a massive flash mob rampaged outside the Wisconsin State Fair injuring 11 fairgoers on Aug. 4, old-fashioned police work quickly led to the arrests of 31 people.
When 25 teens looted a 7-Eleven on Aug. 13, outside Germantown, Md., local police posted a surveillance video on YouTube and visited a local high school with pictures of the perpetrators. Within days, 15 of the 26 suspects were identified.
And just this week, two teens were found guilty of orchestrating a "flash mob" style beating in Philadelphia that left one man with a broken jaw.
