NYPD answers Boston police’s cop-pool karaoke

First it was Boston's police department and two officers' rendition of "God Bless America." Now two police officers with the New York Police Department are throwing down the mic with their version of "cop-pool karaoke" as they hit the beat for Fourth of July.

But instead of a patriotic standard, the officers went with a more contemporary song, Katy Perry’s “Firework.”
