The trial of an officer cleared in the death of a young black man severely injured in police custody has revealed deep and systemic problems within the Baltimore Police Department.

Testimony showed that officers are inadequately trained and routinely ignore rules and regulations designed to keep people safe.

The police commissioner acknowledged the failings Tuesday and announced a new program to help make sure officers read and understand general orders and policies.

The announcement came less than 24 hours after a judge acquitted Officer Edward Nero of assault, reckless endangerment and misconduct charges in the arrest of Freddie Gray, a 25-year-old man who died a week after being critically injured in a police van.
