I live at the end of a dead end street and know what all my neighbors drive , when there is a vehicle parked there with someone in it a call to the pd is issued , the last time it was the housing inspector ( no municp plates on vehicle ) he was checking out something for one of the unts that was for sale and was walking around the building . I have waited at my friends house for them to get home and have had there neighbors call the cops on me , no biggie when I was asked what I was doing there . showed them ID and told them . nothing ever happened.
