I am trying to say that over eagerness in searching for a crime where there is none could cause more damage than it is worth. Those committing the crimes would quickly switch to other methods, but those innocent would be caught by accident. I am also not saying that such people should be left free and unpunished, but that the method proposed could cause far more bad than good, in my humble opinion of course. A legal system of some kind is obviously necessary, but using argument of thinking about `insert a group of people you should care about` can easily lead to abuse of the established laws.
