The New York City police department wants to expand the use of stun guns to subdue emotionally disturbed people and other suspects who resist arrest.
Police officials said Wednesday that preliminary plans call for 450 more officers to carry the electroshock weapons.
The details were revealed a day after officers shot and killed an armed man with mental problems at a Jewish center in Brooklyn.
The proposal is part of a broader review of use of force at the nation's largest police department in the wake of the videotaped death of Eric Garner.
Last week, an officer who appeared to put Garner in a lethal chokehold during an arrest was spared criminal charges. The decision touched off a wave of protests.
