The person recently accused of shooting and killing several patrons at a bar in Thousand Oaks, Calif. may have been at least partially motivated by the issue of gun control, according to a CNN report published Thursday night.

CNN revealed a Facebook post authorities believe was made by the gunman close to his deadly attack:

I hope people call me insane… (laughing emojis).. wouldn’t that just be a big ball of irony? Yeah.. I’m insane, but the only thing you people do after these shootings is ‘hopes and prayers’.. or ‘keep you in my thoughts’… every time… and wonder why these keep happening…

The post, if written by Ian David Long, displays a grasp of how his then-coming actions would affect the inevitable debate about gun control that would follow. Gun control advocates typically mock and brush off attempts at offering “thoughts” or “prayers” after a tragedy involving a weapon usually unless those condolences are followed by appeals for gun control.
