The largest urban riot in the United States since the 1992 Los Angeles riots took place in Cincinnati in 2001. It was a reaction to the fatal police shooting of 19-year-old Timothy Thomas, who was attempting to escape from police officers on foot.
On the third night of rioting, Mayor Charlie Luken issued a curfew, and the riots stopped. However, the riots stopped not because of the curfew but due to an unforeseen factor --- rain. The precipitation stopped the violence in its tracks and limited the damage to $3.6 million.
