Actually, the flash mobs (terror mobs now, really) are roaming the entire city of Chicago. Even normally peaceful and quiet neighborhoods have seen a sudden, rude surge of violence from the mobs. The flash mobs are way far more mobile than street gangs, and they are also terrorists. They open fire on passing buses, trains, and numerous vehicles with automatic assault rifles, and they fire until whatever they are firing at stalls out, and it usually results in dozens of fatalities, even upwards of 50 to 75 per incident, especially during rush hour. And then they storm right in and rob everyone blind. They steal purses, wallets, ID cards, keys, credit cards, cash, traveller's cheques, you name it! And then they also use that info to steal identities, too! Sometimes they fire on public transit for fun, too. The subway is especially dangerous as mobs are known to hide out in corners, as well as those small narrow concrete hallways/walkways that you occasionally see branching off from the subway channel far from the train stops, they have even been found hiding in recesses in the subway tunnel walls, and even behind that large exhaust fan in the Red Line subway, and they open fire on every single train that passes by, blowing up to golf ball sized holes in train walls and killing/injuring scores of people. And sometimes they even hit the train's vital electrical components, causing it to stall and lose power in the middle of the nearly pitch dark subway tunnel. And then once again they storm right in, rifles loaded, and they rob everyone on board, both dead and alive. It has gotten so violent that the city has even mentioned closing down both the Blue Line and Red Line subways indefinitely. The mobs are all over Chicago, from Evanston all the way down to Chicago Heights/Ford Heights, and from the lakefront all the way west to O'Hare Airport.
