I don't know about some of the other angles, but the initial footage is from a camera that Andrew Meyer (the student) gave to another student at the forum (who he didn't know) to film him asking the question. The police are not behind this footage getting out. That said, I don't think him wanting his question taped is any indication whatsoever that he planned for this to happen, and I don't particularly trust some of the assertions made in the police report.
EDIT: and then roachboy had to edit his post
Well, I'll leave this here anyway, in case the info is relevant for anyone else
