For me, this is the type of street photos I would like to take. The individuals are in their element relaxing, and none of them are looking into the camera with suspicion or dread, they're just taking a break.
They're NY's finest, but we all know they have stories. A couple are probably on the take, a couple probably having partner/spouse/alcohol/drug issues, maybe a couple of them are being investigated by IAB for some little shakedown. They have rough jobs and aren't perfect, but still manage to serve and protect.
What an inspiring photo of real life.
