 Exactly, and I think obviously this is early on and it's hard to ask some of these hypothetical questions now. But Josh, you know, like all the surveillance and the scanning of these areas that go into place before the event even occurs, and the drones and the helicopters and devices up above, it's hard to imagine how something like this could have been missed from 200, 300 yards away, a rooftop elevated position. That will definitely be part of the investigation going forward.
