Actually, if they are making calls about legal activities, the best "service" you can provide is to say: "Hey, Dumbass, what he is doing is perfectly legal. What you are doing is tying up police business with ignorant calls. Are you SURE you want me to start writing citations when I come out here?"I agree. And it does happen sometimes. Especially when its continuous calls about legal activity.
Unfortunately the people who make calls about legal activity because it "scares" them are part of the public that the "servants" serve. In fact they have the same right to service as you or I do. Sucks sometimes they abuse this right (I use that term loosely) to bother other good citizens, but it happens.
