Over three nights of rioting in London after the police shooting of a 29-year-old father of four, over 450 people had been arrested and 44 police officers injured. The rioting began on August 6, 2011 when a peaceful march in protest of the police use of lethal force turned violent. According to the Huffington Post, “Hooded and masked youths threw bottles and petrol bombs at police and buildings and vehicles, setting a building, a bus and cars alight.” The source of the violence seems clear, at least with respect to its beginning. Rather than being fueled by greed at that point, anger at a possible abuse of power by the local police seems to have been the motive.
