I put up two bird houses with cameras in them when the neighbors were stealing my firewood.. I also knew they liked to commit acts of vandalism so that was another reason for the cameras. Didn't take them long to figure out there were cameras in them.
A couple years later they falsly accused me of spraying some of their plants with weed killer and called the cops on me.. of course nobody could prove anything but the cops hosted a "mediation" session with all parties and I was accused (even by the cop) of being "creapy" because I hid cameras in fake bird houses..... The cameras were pointed at MY property, not theirs.
F*** them all. The cameras are still there.
