Warren Evans unexpectedly resigned from his post as Detroit’s chief of police Wednesday. He had held the position for under a year and his rocky tenure will probably be marked by a scandal in which a 7-year-old girl was shot and killed by a police bullet in a home raid. The incident was caught on tape by a reality TV crew which was following Evans for a show called “The Chief” about his job as the city’s top cop. The show painted him as a cowboy-like cop and may also have pushed the mayor to ask for his resignation.

The family of Aiyana Stanley-Jones, a seven-year-old Detroit girl killed by a police bullet during a raid early Sunday, filed a lawsuit in state and federal courts, alleging police misconduct in the incident.

At the time of the scuffle, the councilmember was checking on a neighbor whose house was on fire. The police department has since said its officer did nothing wrong. But many residents, particularly in South Phoenix, say this case highlights a deep-seeded racial conflict in the city and a long-standing mistrust between black residents and the police department.
