I assume this includes gas masks so the police can tear gas crowds more effectively. I hate it when some rich college, socialist cigarettes, or black boc starfishs go around and smash the windows of small shops in the name of socialism/equality/fighting evil governments.
I remember hearing about how most of the people during the London riots were looting stores and cell phone companies offered to give the police a list of phones in the area to help catch the looters. Kind of scary how technology can be used in the future to track people down. It also makes me think about those people in the UK who like to call American fat oil thiefs on youtube, who probably stole a TV during the riots.
Also During the the Larry King riots shop keepers in the China Town(the Los Angeles one) would barricade their shops and would use AR15's to fend off looters since the LAPD was busy with the riots.
