WMD ALREADY FOUND?!
Why would the Bush folks keep such politically high-value information secret?
Possibly because, given the sheer number of guerrilla forces present inside Iraq, U.S. investigators believe it would be foolish to leak evidence piecemeal. Sources and methods of intelligence-gathering could be “compromised”–a polite way of saying those helping us or their families could get killed–and the U.S. team’s efforts could be hampered if other would-be informants hold back out of fear.
And with many of Saddam’s former henchmen still around, U.S. investigators tipping their hand could make it easier for Baathist thugs to destroy evidence or sabotage discovery efforts.
Not to be cynical here, but I’m pretty skeptical. While I still think there was a substantial WMD program ongoing in Iraq, this rationale for secrecy is rather farfetched.
