One of the problems the CIA has in doing it's job of collecting and analyzing all intelligence information U.S. agencies collect is that the CIA not only does analysis, but all has it's own personnel out there collecting information. As a result, there is a natural tendency for CIA analysts to favor CIA information gatherers. This has long been noted by other intelligence collecting organizations in the Department of Defense (which actually has more such resources than the CIA.) As a result, the other Department of Defense intelligence outfits continue to do, and advocate, their own analysis. This defeats the purpose of having a "Central" Intelligence Agency.
