A lack of funding to hire new officers and a projected increase in attrition has Washington police leadership concerned about the size of the force in the coming years. Lanier told The Associated Press that the department has about 200 fewer sworn officers than it did less than two years, budget problems have stalled recruiting and officers who joined the force during a hiring surge about 25 years ago are preparing to retire en masse.

District of Columbia Police Chief Cathy Lanier says New York City's stop-and-frisk policy probably helped reduce crime but became a less acceptable police tactic as communities there became safer.
Lanier spoke Friday at an American Bar Association conference, where she discussed tactics to reduce homicides.
A federal appeals court on Thursday blocked a judge's ruling that found that stop-and-frisk discriminated against minorities.
In response to a question, Lanier said the policy may have run into problems by not requiring officers to provide detailed explanations for why individuals were stopped and frisked.
