Investigation reveals how rare it is for police officers to face charges for lethal force

Lorning Cornish celebrates at the corner of West North Avenue and Pennsylvania Avenue after Baltimore authorities released a report on the death of Freddie Gray while police in riot gear stand guard on May 1, 2015, in Baltimore, Maryland. Marilyn Mosby, Baltimore City state's attorney, ruled the death of Freddie Gray a homicide and that criminal charges will be filed. Gray, 25, was arrested for possessing a switch blade knife April 12 outside the Gilmor Houses housing project on Baltimore's west side. According to his attorney, Gray died a week later in the hospital from a severe spinal cord injury he received while in police custody.

When Baltimore's top prosecutor Marilyn Mosby announced criminal charges against the six officers involved in the death of Freddie Gray last week, many were shocked. It's rare for officers to face criminal charges in such situations.

A recent Bowling Green State University and Washington Post investigation called "Thousands Dead, Few Prosecuted" looked into how hard it is for police officers to be charged after fatally shooting someone while on duty. It was published one day before Freddie Gray's arrest.
