Profile: Joseph O’Brien

Joseph O’Brien was a participant or observer in the following events:

Double agent Ali Mohamed, who became an informant for the FBI in 1990 (see 1990), apparently works as an FBI informant again, obtaining intelligence on some suspects at a San Jose, California, mosque. But he is never polygraphed, even though this is standard procedure. Retired FBI agent Joseph O’Brien will later complain, “One of the most unbelievable aspects of the Ali Mohamed story is that the Bureau could be dealing with this guy and they didn’t” polygraph him. “The first thing you do with any kind of asset or informant is you polygraph him and if the relationship continues, you make him submit to continued polygraphs down the line.” FBI agent John Zent becomes Mohamed’s handler. [Lance, 2006, pp. 95-96] Apparently Mohamed will be given a polygraph test in 1993 and will fail it (see May 1993).

Double agent Ali Mohamed is interviewed by the US military about al-Qaeda, but what exactly is said is uncertain because the interview files are supposedly lost. When Mohamed’s FBI handler John Zent interviewed him in May 1993 (see May 1993), he mentioned al-Qaeda training camps. FBI agent Jack Cloonan, who will later investigate Mohamed, will recall, “John realizes that Ali is talking about all these training camps in Afghanistan. And starts talking about this guy named bin Laden. So John calls the local rep from army intelligence” and arranges for them to interview him. A special team of army investigators shows up from Fort Meade, Virginia, which is the home of the NSA. “They bring maps with them and they bring evidence.… And so they debrief Ali, and he lays out all these training camps.” What else he may reveal is not known. Cloonan is not sure why Mohamed volunteered all this vital al-Qaeda information. Earlier in the year, FBI investigators discovered that Mohamed stole many top secret US military documents and gave them to Islamic militants (see Spring 1993). However, Mohamed faces no trouble from the Defense Department about that. FBI agent Joseph O’Brien will later ask, “Who in the government was running this show? Why didn’t the Bureau bring the hammer down on this guy Mohamed then and there?” Whatever Mohamed says in this interview is not shared with US intelligence agencies, even though it would have obvious relevance for the worldwide manhunt for Ramzi Yousef going on at the time since Yousef trained in some of the camps Mohamed is describing. Several years later, Cloonan will attempt to find the report of Mohamed’s interview with army intelligence but “we were never able to find it. We were told that the report was probably destroyed in a reorganization of intelligence components” in the Defense Department. [Lance, 2006, pp. 130-131]
