Critics of NYPD street stop policy seek big changes; skeptics say change could come at price

Lawyers for men who sued the New York Police Department are asking for major changes to how the department conducts street stops that could affect policing nationwide.

A policing expert working with the Center for Constitutional Rights says a comprehensive change must be made in order to fix race-based stops. Professor Samuel Walker says changes must be made to training, supervision and discipline. An expert for the city says the changes aren't necessary because they are already done by the department.

About 5 million stops have been made during the past decade, mostly of black and Hispanic men, and the suit alleges many were wrongly stopped solely because of their race.

A federal judge will decide whether changes are needed. She isn't being asked to ban the tactic.
