as someone who typically is very proactive about citing my comments (see my post history) I'm going to claim 'afaik' - as far as I know - as a citation in this case because I'm clearly indicating a nonauthorative claim here.
This would be a case where you're asking me to prove the negative...can you find instances of Swatting occurring with similar resulting violence in, lets say, Japan or Western Europe?
