when a policeman doesnt hear what I hear, what should I do?

dear friend
the least thing you can do is to record a film our just their sounds and replay it for your policeman or maybe try another policeman...

stop being a busy body nobody likes that the cop is simply ignoring u because he hears from u 2 often instead get a video camera and record whats going on and if it is a crime take it to the media

Run....

many cops nowadays just want a job for living; they don't really do what they're supposed to do.

Depends on what your hearing, if your an habitual caller and the reports are unfounded they may simply feel they are waisting their time checking it out. It is also possible that if its a low priority call and other stuff is going on they may not give it the attention that you think it needs.

Try tinfoil on the head. It really works, makes the noises "go away"

what is it that you hear

The sheriff's department can start a file on you if you do not believe that city police can hear the voices that you hear.

Contact the F.B.I. ( Federal Bureau of Investigation ) or if you live in a City, contact the County Sheriff's Office.
