The federal monitor overseeing changes at the New York Police Department has asked a judge to sign off on modified policies for making street stops.

The changes to the NYPD's patrol guide proposed Friday would spell out ways to ensure stops are lawful and to clarify a ban on racial profiling.

The proposed wording tells officers they're allowed to approach people to ask questions but makes clear people can refuse to answer. It says if officers decide to stop and frisk someone, they must be able to articulate a specific justification for it.

A judge ordered changes in 2013 after a class-action civil rights trial in which black and Hispanic men said police had unfairly targeted them because of their race.

The NYPD said Friday it would welcome the changes.
