There is not enough detail for me to comment on your situation but I have had 'situations' also.
It is frustrating but it is not all the cops fault. I recently had to call the state HP to report a kid coming around a corner at an excessive speed with his brother hanging onto the outside of the car with his stereo so loud that he set off a neighbors home security alarm. The cop acted as there was not much he could do and kept making statements that I had called because I had an 'issue' with the kid. I did but that was besides the point. After about an hour of discussion with the cop and his discussions with the kid and the kid's parents and discussions of what can and cannot be done (including citizens arrest) I have not heard the kid's stereo a single time since the incident and he drives very carefully in the neighborhood. The cop also said to the kid that if he eversaw the kid's bronco on the street he should make d@amed sure that he was driving very carefully.
Was I disappointed with the cops response? Yes. Did we work out the problem? Yes.
