CHRIS BURY:

With so many questionable police shootings caught on camera during the past two years, how police are trained is coming under greater scrutiny, along with calls for reform.

Studies by The Washington Post and The Guardian found police in this country shot and killed about a-thousand people last year — almost three people a day.

The post found 987 cases, and the guardian, 1,014. The country's 18,000 police departments, on average, train officers for only a total of 15 weeks before rookies hit the streets.

Maria Haberfeld, a professor of police science at the John Jay College of Criminal Justice, in New York, blames poor police training–not rogue cops– for many questionable cases of lethal force.
