Okay, I will agree that if they are sitting side by side for hours doing nothing then that is not productive. But I also know that cops do not have a desk to work at and when they have to fill out a report sometimes instead of driving all the way to the station it is more productive to stay in there work area and fill that report out in there car. And while doing that it is also safe for them to have someone parked next to them that can pay attention to things around them so that they do not get sneaked up on. Again it helps to know all the circumstances before passing judgment. And while I'm thinking about it the OP was not in complaint to them sitting around doing nothing. It was a complaint about them doing there job. And to many of them responding.
