Milwaukee has imposed a 10 p.m. citywide curfew for teenagers, following this weekend’s uprising sparked by the fatal police shooting of a 23-year-old African-American man named Sylville Smith. On Sunday, Wisconsin Governor Scott Walker also activated the National Guard after local residents set fire to police cars and several businesses, including a gas station, Saturday night. Police say Smith was shot by an officer following a traffic stop. Police Chief Edward Flynn says Smith had turned toward the officer with a gun in his hand. An autopsy conducted Monday shows Smith was fatally shot in his chest and arm. Milwaukee is considered to be one of the most segregated cities in the country.
