1966 Chicago West Side riots

The riots began on July 12 after an ex-Convict named William Young, who was wanted for armed robbery, attempted to evade arrest at a liquor store on the 100 block of South Pulaski road. Young ran away from officers Biaggio Panepinto and James Rizzi and began screaming that the officers were trying to kill him, attracting a crowd of around 200 people. Young was caught in an alley but the mob encircled Panepinto and Rizzi and began demanding that they release Young. Panepinto and Rizzi were eventually rescued by other officers, but the mob began to loot the liquor store, beginning the unrest on the West Side.[2]

Unrest quickly spread throughout the West Side. On July 13, around 200 youths looted a drug store and threw stones and fired shots at police, wounding seven policemen. Several drug stores, liquor stores and supermarkets were looted and set alight, with rioters pelting responding firemen with stones.[3] During a raid on an apartment building, 21 members of "paramilitary group" were arrested. A police captain said he received reports the group was planning on waging guerrilla warfare and had caches of automatic weapons and explosives stashed throughout the city.[4] At one point, services of the Lake Street Elevated train line had to be cancelled as snipers had fired at passing trains several times.[5]

By July 15, 1,500 National Guardsmen had been deployed to patrol 140-block area of the West Side and calm returned to the West Side, though looting and fires continued to be reported. The troops had been given orders to shoot. Over 30 people injured during the riots, including six firemen and six policemen who had been shot. Two civilians, a pregnant 14-year-old and 28-year-old man, were killed by stray bullets from shootouts between police and snipers.[5] More than 200 people were arrested on July 14 alone.[4]
