Clearly drawn is hard to prosecute (and one might argue shouldn’t be prosecuted, since obscenity laws are just… weird). However, the stuff that is photorealistic can be treated, legally, like the real thing.

Fun fact it’s already illegal. If it’s indistinguishable from the real thing it’s a crime.

There’s mixed evidence of whether or not mass shootings have a contagion effect, that people who are already “primed” see this shit on tv and decide that today’s the day.

Or it could just be chance.

But maybe, here’s an idea, we don’t let people who make terroristic threats have guns. I don’t care about what kind of gun, if you credibly threaten to murder a bunch of people, no gun for you.

In this case, yes. Visually indistinguishable from a photo is considered CSAM. We don’t need any new laws about AI to get these assholes. Revenge porn laws and federal CSAM statutes will do.
