Well, I certainly wouldn't sit there and do speed enforcement. In fact, I preferred to NOT sit anywhere and just drive around doing this thing called patrolling. Could find way more violators doing stupid things than just sitting somewhere waiting for them to come to you. Plus, the ominous vehicle with lights all over it and "police" in big bold letters usually got me plenty of voluntary compliance. Didn't have to do anything for that. Work smarter. Incidentally, most of our focused enforcement actions were complaint driven. And of course, most of the violators were the complainers.
