What does the NYPD do?

Recently moved to New York and in my few weeks here I've seen:

A car run a red and block a police vehicle with lights on. Police just asked him to move to the side

A traffic officer guiding the flow of traffic asks someone to stop. That person gets out of the car and starts swearing at her and threatening her

A police car stopping right of way traffic to let people on dirt bikes race through red lights

I've never seen a police department take such disrespect and inaction. I thought NYPD was supposed to be the best and they seem like a bunch of pushovers
