Ayoobs article is badly titled, as it does not go into the real lessons learned from the blood of the FBI Agents. As I posted earlier in this very thread:
1. Attitude is all important. TODAY could be THE DAY for you. Train, prepare, and act as though it is.
2. Training matters - at the time, the FBI did not teach their own personnel vehicle stops tactics. I taught them for my Federal Agency, and we never taught pulling up alongside the suspect vehicles, nor ramming them.
3. Shot Placement matters - not the caliber, kind of ammo, or number of rounds in the gun. As we said, a single .22 short in the brain stem is better than a hit in the pinky with a .500 S&W. It's interesting but ultimatly useless to anylise to the 100th degree the guns and ammo.
4. Information sharing is critical - McNeil was asked by one of the agents, just before the shooting started, if they should notify the local PD. His reply was "No, their assistance will not be needed."
5. Identification matters -The first calls to 9-1-1 were "there is a bunch of white guys shooting at a bunch of white guys". The first officers on scene could not help the FBI, because they did not know who was who.
NONE OF THIS FAULTS THE AGENTS! They did the best they could with the training, information, and abilities that they had. Their agency failed them, mostly by allowing the "It's not going to happen to me!" mindset and the failure to train them for a clearly probable event - an unknown risk car stop. I have been in similar circumstances, but had already sought out additional training beyond what my agency offered. In one case, it saved a number of lives, including my own.
(The information I base this on includes, but is not limited to: The Treasury Dept. report of the incident; seeing all 3 of the police videos about it; seeing the lecture by the lead investigator at the Federal Law Enforcement Training Center, and 27 years as a Federal Agent, 25 as a firearms instructor.)
