Black cops in St. Louis stuck between public, fellow officers

During a peaceful protest moments before St. Louis would erupt into three nights of racially charged riots, five people confronted a black police officer alone in his Jeep."How do you sleep at night?" Lisa Vega, who is Hispanic, asked the officer through an open window.Such questions are typical of what African-American police officers face every time a white colleague kills a black man in the United States.
