We have always had the opportunity to call the authorities when we see something dangerous or illegal.
However, I would not call police if I saw a bank of lights burning x number of hours per day at my neighbor's house but I would call them if my child reported to me that he/she was approached to deal for the neighbor; and would not call the police if another neighbor had a rottweiler or pitbull but would if said dog threatened me or others, I would NOT call the police or FBI if dark-complexioned people moved in next door and kept odd hours but would if I saw that they accidentally dropped an odd stuffed pipe complete with protruding wires.

Unless the police and other law enforcement people want to be REALLY busy flitting around and busting innocent people, I think it's dumb beyond belief to set the citizenry against itself.
