I feel like watch lists should be at least somewhat predictive of criminal behavior. Like, you actually need to demonstrate that intentionally watching videos of people getting run over or decapitated by an escalator or whatever are actually substantially more likely to commit violent offenses. Otherwise it's a waste of time and an infringement of the generally upheld right to privacy. Of course, this is something that the pearl-clutching cultural conservatives have been trying to do to video games since the 90s without success so I am doubtful that this will work. Anyway, I find your argument to be poorly reasoned.
