A federal monitor overseeing changes to the New York Police Department's stop-and-frisk policy says the effort is moving in a positive direction, but there is much work left to be done.

Peter Zimroth filed his first report Thursday. He says the initial work has been on better training for new recruits on what constitutes a legal stop.

A judge ordered changes in 2013 after a civil rights trial in which a dozen black or Hispanic men said they had been unfairly targeted by police.

The judge found the department had unintentionally discriminated against minorities and ordered reforms — but she did not end the policy.

Since the ruling, stops have plummeted from an all-time high in 2011 of 685,724. There were 46,235 in 2014.
