Lost Tapes

I think a question which must be asked is why is that the CIA have destroyed the tapes of the interrogation of a substantial number of combatants, insurgents or whatever the 'enemy' are to be known as.

Bearing in mind that no evidence could be found of maltreatment of prisoners, as was said in the statement to parliament only last week by John Hutton, could it be that the evidence has been destroyed. That is why there is no evidence.
