Missiles for Olympic Protection Found Unguarded in London

Well, everyone has heard about the controversy surrounding the British military putting surface-to-air missiles on top of residential apartment buildings to provide more security for the upcoming Olympic Games.  However, this video is even more disturbing.  Apparently some of these missiles were found just lying around with no one from the military anywhere around.  Do these guys have their act together, or is this a harbinger of a false-flag operation in the making?
