Nearly a thousand times this year, an American police officer has shot and killed a civilian. In a year-long study, The Washington Post found that ... the great majority of people who died at the hands of the police fit at least one of three categories: they were wielding weapons, they were suicidal or mentally troubled, or they ran when officers told them to halt. Although black men make up only 6 percent of the U.S. population, they account for 40 percent of the unarmed men shot to death by police this year. The FBI is charged with keeping statistics on such shootings. Fewer than half of the nation's 18,000 police departments report their incidents to the agency. The Post documented well more than twice as many fatal shootings this year as the average annual tally reported by the FBI over the past decade. The research also noted whether victims were mentally ill or experiencing an emotional crisis. Officers fatally shot at least 243 people with mental health problems: 75 who were explicitly suicidal and 168 for whom police or family members confirmed a history of mental illness. Most of them died at the hands of police officers who had not been trained to deal with the mentally ill. An average of five officers per year have been indicted on felony charges over the previous decade; this year, 18 officers have been charged with felonies. Such accusations rarely stick, however.
