10mm being issued to Feebs came about directly due to this shootout. 40 came about because Feebs thought the 10 was too much. Now we're back to the 9 because all the agencies that followed the Feeb's lead still are. If somebody would have just took the time and aimed for the head there wouldn't have been so many casualties. It was a training failure on many levels, not a failure of equipment or ammo.
