The news today doesn't know how to write stories or research anything without live camera footage. They've gotten lazy, relying on just narrating what we can all see for ourselves on grainy home-made videos.
The video clips of the wave and the dead are coming in now... so we'll be seeing more coverage on the news soon.
Where have you seen clips of the wave? A couple of vidcaps is all I've seen. I'm sure there must be a dozen or so priceless vidos out there somewhere.
