Law Enforcement on Trial in America

In Charleston, South Carolina cellphone video appears to show criminal conduct by police officer Michael Slager. He was fired and charged with murder shortly after the video went viral. It's the most damning in a series of videos that have created a crisis of public confidence in law enforcement.

Such recent body-cam and bystander videos appear to confirm the worst accusations against police in some parts of America. They show what looks like racial profiling, abuse of force and tampering with evidence. They suggest that some cops believe they can get away with murder. Everybody agrees police face danger on a daily basis, but there's a growing consensus that steps are needed to counteract a loss of public confidence. Is better training what's needed to overcome deficiencies in cop culture?
