Spycatcher all over again?

http://news.bbc.co.uk/1/hi/uk/6334769.stm

"A coroner's official later said he had been told the video - classified secret by the US - would be shown in 
full to only the coroner and the Hull family".

I wonder what state secret would be outed by allowing the public and the press to view the video? Do you think 
anybody has broken it to the US government that the BBC and Sky News have been broadcasting it for several hours 
already? I think that the authorities could end up looking as silly as the Thatcher government did during the 
Spycatcher hearings if they don't buck their ideas up.
