Just like they confiscated the BBC film crew's video of the scene where Flanagan allegedly committed suicide because it was 'evidence'... that subsequently never saw the light of day.
They did a better job of controlling the information this time... can't have any unauthorized video floating around...
Well, as AbaraXas said, "let's be fair" here a bit.
I can understand why 'authorities' would want to 'protect' victims' families from seeing gruesome bloody headshots or God forbid, video of somebody in the act of being killed (after saying "Christian").
So in a way, I understand the order.
But, not one of the students has come forth on even cable news to give any statements. That's weird and highly unusual, IMO.
