A Brooklyn councilman wants the city to consider replacing the New York Police Department's vehicle windows with bulletproof glass.

Politico New York reported Councilman Jumaane Williams plans to introduce the bill, currently cosponsored by at least two other members, to help cops feel better protected while working their beats.

Williams' bill echoes an attempt by New York state lawmakers in late December after the shooting deaths of two police officers in Brooklyn using state money.

At the time, NYPD Commissioner Bill Bratton told state senators he would rather invest money into protective ballistic panels for the about 9,000 vehicles cops use than on expensive glass.

Bratton estimated replacing windows with the glass would cost about $50,000 per car.

"We want to look into how cost-prohibitive it actually is. This is only the beginning of the conversation," Williams told Politico New York. 

In January, the City Council and Mayor Bill de Blasio jointly announced City Hall would spend $7.3 million for 13,000 state-of-the-art bulletproof vests that were distributed in May.
