Teenager testifies in challenge to stop and frisk tactic he was handcuffed while walking home

A teen and a man in his 20s were the first people to testify about their encounters with police at a federal trial about the New York Police Department's practice of stopping, questioning and frisking people.

The two, who are black, testified Monday that they were wrongly targeted because of their race. Lawyers say the trial will include stories from other black and Hispanic men who say they also were targeted because of their race. Police officers and criminologists are scheduled to testify.

Police have made more than 5 million stops in the past decade, mostly of black and Hispanic men.

The suit seeks a court-appointed monitor to oversee changes to how the police make stops.

A federal judge will rule on whether the department must make changes.

The civil case continues Tuesday.
