I imagine this sort of thing happened all the time.
Look at it this way: If the CIA had provided the FBI with information on Bayoumi when the FBI requested it, their target might have been arrested/prosecuted/deported and they would lose the lead.
Also, back in that era, information sharing between CIA and FBI was not even permitted.
"On Monday, Senator Lindsey Graham and I asked the Justice Department to produce any documents they may have in their possession relating to Jamie Gorelick's involvement in establishing policies preventing the sharing of critical terrorism-related information between intelligence and law enforcement officials. It is the fact that those have now been made public and, indeed, posted on the Department of Justice's Web site at www.usdoj.gov which brings me back to the Senate floor to briefly mention why I think Ms. Gorelick's testimony is even more important to explaining what she did as a member of the Justice Department under Janet Reno to erect and buttress this wall that has been the subject of so much conversation and why it is so much more important that she do so because the 9/11 Commission's credibility is at stake."
