I think we may be splitting hairs here. I didn't have Clinton's exact words at hand. Clearly he compared Bush's efforts unfavorably with his own. He used as one example a total falsehood, that Bush "fired" Richard Clarke, the NSC terrorism expert. Certainly Clarke hadn't accomplished much during 8 years with Clinton, so even if he had been canned I don't know what that would prove. I don't know exactly what kinds of warnings Bush was given or how specific they were. The 9/11 docudrama implied the failure was at the CIA, where they made the decision not to issue a general alert to the airlines. I'm not even sure how much good that would have done, given the lax airport security and the crippling effect political correctness had on screening. "Negligence" is a legal term that implies a failure to use reasonable caution. I'm sure there were levels of the government that indeed were negligent, but I haven't seen evidence to convince me that Bush personally was negligent. Clearly he didn't fully appreciate the seriousness of the threat, but a mistake is not the same thing as being negligent.
