I've seen the "X causes violence" routine before - first in comic books, then in D&D and (of course) all the other role playing games, then in the first round of video games and...well...you get the picture. It made no sense before, but it allowed the politicos to deny reality (again) for long enough so that no one would demand that they actually DO something that made sense.
