The Jehovah’s Witness Protection Program

When I was a kid my mom had a tradition where whenever there was the slightest inkling that the Jehovah's Witnesses were on the prowl in our neighborhood she would shut the blinds lock the doors and tell me to be quiet in the hopes that they would go away without noticing us.

My hope would be to use current pattern recognition technology to detect these unwanted visitors and somehow discourage them from shoving their religion down the throats of the uninterested. The recognition system would be fairly easy. Three cameras arraigned around the door wound scan, on detection of movement, for visible copies of AWAKE! Or The Watchtower. If the PR software detects the suggested parameters then the deterrent system would be activated. I tend to lean twards the stereotypical evil villain sort of things, trap doors, stairs to slide, ambient pepper spray, and the like, but the possibilities for deterrents are endless, as are the applications. I used the Witnesses as an example but you can set the parameters for white shirts and bicycles for the Mormons or some Pattern Recognition software is advanced enough that you could even target specific unwanted relatives.
