If you want examples of events that could be reasonably interpreted as “this sort of thing”, the son of the guy who tried to assassinate Trump the second time was mysteriously arrested for possession of CSAM a week after his dad was arrested. I’m inclined to believe that the base rate of people being into that stuff is reasonably low so whenever I hear about someone being charged with it in relation to a completely unrelated major news story it gets my spidey sense tingling.
