To be honest, if it prevents that one guilty man from carrying out such high degrees of abuse to a dozen children, I can’t say I’d say no.
I want to stress that this isn’t sensationalist grandstanding like wanting to ban rock music or video games or spying on all digital communication in the name of protecting the children. It’s just the pragmatic approach towards preventing CSAM in an age where the “know it when I see it” definition of pornographic material is starting to blur the lines.
