Barry Mawn

From 9/11 Encyclopedia:

One of the few friends of ex-FBI terror specialist John O'Neill, who supported him, even after it came out, that he should be fired because of a "lost briefcase" and increased trouble with Thomas Pickard  and Louis J. Freeh (->). Mawn was involved in the "dirty Boston FBI office"-case http://www.laborers.org/HartfordCourant_12-23-99.html 
The EgyptAir investigation http://www.yowusa.com/authors/srussell/4Q99/flight990_1/EgyptAir_Flight_990_1.htmL ".

..FBI special agent Barry Mawn continued the claim that there was no evidence of criminal activity. 
He said that a Flight 990 hotline had received 85 calls but none were significant.

Mawn, O'Neill's former boss, dismissed his lost briefcase as "nothing,", something that O'Neill would have received a verbal reprimand for. O'Neill, he said, wanted to stay on with the FBI and clear his name, but he'd already decided to retire and enter the private sector...." It appears, that Mawn was later either part of a plot or had something to hide. He was the one, who had to classify the famous "passport in the rubble" (->) on September 16th 2001, which was found in front of Building 7, Vesey Street. A building which was under control by military company Blackstone (->), the CIA and DoD, who had both offices in that building: "FBI Assistant Director Barry Mawn did not disclose the name on the passport or other details, but the discovery prompted an intensive search for evidence..."

As later revealed by ABC, the passport belonged to one of the officiall hijackers, Satam Al Suqami. Mawn was in charge of the New York Anthrax cases: Due to a November 11th, 2001 press conference with Tom Ridge of the Homeland Security, Mawn protested during the investigation, that the original source was based on US -Military: "Q: Barry Mawn, of the New York FBI is quoted in today's Boston Globe as saying it was produced in the U.S. He said, "It was made here." Is that incorrect? GOVERNOR RIDGE: Well, he may have a suspicion that it was made here. But, clearly, in talking with the FBI Director and other individuals involved in the FBI, there is no credible evidence that points specifically..."

Mawn was then forced to put the Anthrax-NBC investigation on hold: "...Although the F.B.I. was notified on September 25 about suspicious letters sent to NBC, neither the letters, nor the powder residue inside them were tested until nearly two weeks later, and then only because a private doctor notified city public health officials about a troubling skin condition in the news assistant who had handled the mail, officials acknowledged yesterday.

Only a few months later, on March 22nd, 2002, Mawn resigned at the FBI. Mawn almost started a job as Boston airport's security company Massport as a security chief http://www.bostonherald.com/news/local_regional/port04092002.htm "..
.Robinson said hiring a CEO will allow Massport to then turn its attention to hiring a new director of security. A number of candidates are interested in the job - reportedly including retired FBI supervisor Barry Mawn..." Mawn later appeared in a John O'Neill-documentation by PBS. Mawn, as late as Nov 2001, was being considered for a move up the ladder, as reported in TIME magazine:
