The "recent convert" material appears to come from the police - at least, that's where I saw it attributed by CBC yesterday, though I can't find the article now. Media are doing everything they can to try to spin this and another recent incident into a campaign, but... yeah, given his history and everything we know thus far, particularly the details in this article, the picture I get is of someone who was slowly sliding out of control and knew it.
That's not stopping the security theatre, though - military personnel are currently under orders not to post pictures of themselves in uniform, to be wary of new social media contacts, and to travel in pairs, and government facilities as far away as here in Nova Scotia have been effectively closed to the public. That... scares me. I don't trust the Harper government at the best of times, and right now it has a hell of an excuse to do a lot of troubling stuff. On the upside (and this is something I'm hugely proud of), we're steadfastly refusing to be terrorized. Hopefully that'll limit the damage that can be done.
