police standby as harassers go all out

I was waiting outside our office with a group of colleagues. A guy was hanging outside the window of his car (3 others were also in the car) and verbally harassing everyone nearby or passing his car. At one point, a girl passed by on her bicycle and the guy yelled at here: do you want to come with us? I want to come in your mouth. A police car was in front of him and the police officer did not intervene during any of his verbal assaults on people.
