I hate that, but that's for the greater good. We could prevent virtually all crime if we were all required to be under video, GPS, and audio surveillance at all times and only be permitted to leave your home to go to work or shop for basic goods, otherwise face a lifetime in prison. However, that goes against common sense and agreed upon basic human rights. You should be free of government/police surveillance unless there is a warrant with very specific and limited conditions and parameters, I feel that is the spirit of the 4th amendment and bill of rights in general.
