Who’s policing the police? Why no one tracks police use of deadly force

The family of Miriam Carey, the 34-year-old woman who was shot to death outside the Capitol a few weeks ago, has asked for a federal investigation into her death.

"A lawyer representing Carey’s family has sent a letter to the U.S. Attorney General claiming police violated Carey’s civil rights and used excessive force,” reports a local Stamford, Conn. outlet, where the slain mother was from.

When D.C. police killed Carey in October, the country was once again thrown into a conversation around the use of deadly force—especially as Carey’s 14-month-old daughter was in the back seat of the vehicle as police fired on it.

That tragedy is the most recent in a series of high-profile cases in which unarmed black suspects have been killed by authorities under controversial circumstances.
