Did not catch Robert Hanssen, Aldrich Ames, (and perhaps who else ?) much earlier, in large part because they never gave enough credence to the work of James Jesus Angleton.
Ignored pre-9/11 warnings by the female SA about Saudi taking rudimentary flying lessons in a 747 simulator in Minneapolis. Had he been interrogated earlier, and his bank account transfers reviewed, he would have rolled on the whole event, long before it happened. (This was one symptom of what was then a Bureau that was then very stupidly so chauvinistic that many smart, very promising female SAs gave up and quit.) It’s a shame they never caught the two St. Louis-deplaning failed hijackers from 9/11, but there was no malfeasance there.
Did not work the Sami al-Arian case nearly well or early enough. There are still many unreported pre-9/11 activities involving al-Arian being flown to campuses across the country by Iranian flight students at Phoenix East Aviation who were supposedly getting flight hours in King Airs so they could get airline jobs. It was all a setup so al-Arian could travel with no records of him being a passenger on the flights. Iranian advanced flight students would fly from Daytona Beach to the small Peter O. Knight airport in Tampa; where there is no control tower, security or record of anyone’s coming or goings; pickup al-Arian; then fly him to colleges across country where he would secretly radically lecture to MSAs; then back to Tampa, then fly the a/c back to Daytona; with never any record of al-Arian being a passenger, or going anywhere. Al-Arian’s cover was as a professor at USF, but in reality, he was the head of Islamic Jihad in the US, and they missed it early, and then screwed up the case when he was arrested.
This all may be replaced by the actions the currently named SAs and others in the Hillary Email and Trump investigations. The “Insurance Policy” thing may be something way beyond what we even know now.... but this entire matter is not “ripe” yet, nor is its full extent known, although I expect it to be huge. Quite frankly, this may amount to an attempted “administrative coup” against President Trump.
Waco, but that was a decision forced on them by Janet Reno personally, not internal to Bureau.
The entire Top Hat-Fedora fiasco, but that was on Hoover’s watch, more than 30 years ago.
Sloppy lab work of a few years ago, then lying about it.
Before the second raid on Waco. What plans did they make in saving the children? Clearly there was no intent on saving anyone.
The FBI/BATF inserts 6 canisters (1.5 gallons) of CS and over the next 6 hours FBI shot 400 Ferret rounds at 3.7 grams each" This WAS posted at www.justice.gov now archived. The building was a 4,500 sqft building. Which by all calculations that was far above the percent needed for combustion
