Go Flock Yourself (GFY) is a simple tool for protecting privacy by obscuring spy cameras without damaging them. Simply stretch a rubber band around the tines of the GFY. Then put a grocery bag around those tines. Slide the apparatus over the spy camera and then pull down gently so the rubber band slides off the apparatus and cinching the bag to the spy camera. The screw head fits the typical handles for things like brooms, paint rollers, etc. Disclaimer: You should only be using this apparatus on property you have a right to touch. For instance, let's say you want to go skinny dipping in your pool but don't want your camera to record you because you can't trust cloud providers to not have a data leak and then have your junk on the internet. Then this would be a very handy tool. I merely made it. You are responsible for how you use it.
That depends on the crime. They barely treat rape as a crime - that’s why they barely investigate it. Start interfering with their precious surveillance state, though, and you might very quickly find yourself a much, much higher priority than the guy who murdered five sex workers last month.
