Intelligence failures do not take place overnight...they take a long time to create and just as long to detiorate.
A very good friend of mine has been in the FBI for more than 15-years (BTW: a field I wanted to pursue coming out of college and was told your white/male/single, you have no chance of getting in).
Obviously he tells me nothing about cases and should I ever see him in my area and jokingly mention it he says, "don't know what you're talking about."
He did tell me this; intelligence is a dirty business and if you want dirt on scumbags you're going to have to deal with the likes of it. Once you have a source unless you totally leave them hung out to dry you'll have them forever.
He said the quality of intelligence eroded as cuts in the deparments took hold over the 90's, which is why I have disdain for clinton; he was given a world where the cold war was over and thought he didn't have to do a damn thing. (Oh yeh...he did make 30 requests to the taliban to push out OBL)
As far as 5ever's comment on the investigation; I totally understand your thoughts but in the present state of things, with an election in November and democrats stating in poll after poll that nominating a candidate with a slight chance of beating the President (kerry) is more important then the candidate they feel is best suited to handle domestic issues (dean), you'll never get the truth anyway. Just a bunch of partisan politicians who want to slant information towards their party.
Did you watch the questioning of Kay last week? Did they question him to get the truth or try and squeeze answers from him they thought would best fit their agenda's?
