Aerial views showed police were deploying in what can be described as a "collapsing containment" strategy. Slowly herding the now-violent demonstrators into a smaller space and easier containment.
Police were now being pelted with thrown objects, and while field force front lines remained intact, arrest teams of ample officers conducted forays into the mobs to arrest select targets, and then whisked them back behind the lines. These arrest forays were repeated again and again.
Meanwhile, the crowds turned mobs had turned violent, throwing objects at police, wearing the typical Black Bloc "uniform" (all black clothing, bandanas, hoodies and backpacks containing improvised weapons. As organized as police were, the anarchists appeared nearly as well organized, and were clearly acting according to their own plan.
Suddenly, at least one TV station ground reporter said there was a splinter mob breaking into a Foot Locker store, just beyond the police containment area. The reporter provided live coverage as the mob broke windows, ransacked and looted the store. Then, emboldened by their "success," they searched for more targets. Soon, the mob was rampaging, breaking windows with hammers, looting, spray painting buildings, setting trash-dumpster fires and rioting.
Sixty to 80 businesses were damaged, vandalized, or looted. Ultimately, 78 rioters were arrested for various charges—mostly misdemeanors—but 12 for felonies that included assaulting and/or resisting police, rioting, and looting.
