When the federal troops arrived, they found the city full of fear. The Army believed that its first task was one of maintaining its own order and discipline. Second, it strove to establish a rapport between the troops and the citizens as a basis on which to build an atmosphere of calm, trust, and order. The soldiers provided coffee and sandwiches to the beleaguered residents, and an atmosphere of trust gradually developed. It became clear that the mutual fear between the police and the citizens had only intensified the catastrophe. Lessons which had been learned two years earlier in Watts by the police and the Guard had not been applied in Detroit. Law enforcement officials again overreacted and used high-powered military weapons in a crowded civilian situation. This overreaction presented as much danger to innocent, law-abiding citizens as did the violence of the rioters. There had also been a tendency to treat the residents, en masse, as enemies and thereby to weld them into a hostile community. The federal troops demonstrated that a calm, deliberate, and open display of force was much more effective in restoring order than shooting at any frightening or suspicious target. By the time order was restored to Detroit, forty-three people had been killed. Thirty-three were black, and ten were white. One Guardsman and one fireman were among the casualties. Some of the other white victims had been killed while they were engaged in looting. Damages were originally estimated at five hundred million dollars, but later estimates reduced the damage drastically. Again, as in Newark, there was evidence of police brutality during the riot. The police were charged with brutality and murder in an incident which occurred at the Algiers Motel. After hearing that there had been a sniper in the building, the police riddled it with bullets. Then, they entered and searched it. In the course of questioning its inhabitants, three youths were shot and killed. In turn, the police and the Guard accused the rioters of widespread sniping. Twenty-seven rioters were charged with sniping, but twenty-two of these charges were dropped at the preliminary hearings for lack of evidence. Later, one pleaded guilty to possessing an unregistered gun, and he received a suspended sentence.
