I was working with an FBI agent on a telecommunications fraud case (I put a former employer who screwed me in federal prison for 18 months) shortly after this happened. He knew I was a gun nut and loaned me the official FBI training VHS recreation of this shooting. There was indeed much to be learned.
As a little side note....The FBI weapons section (or what ever it is called) made the recommendation that the FBI switch to the 10mm for improved stopping probability. However the women and small stature men in the FBI had great difficulty controlling the original 10mm loading. So the FBI ordered down loaded ammo for the 10mm; S&W looked at the performance of the loading and said "We can achieve that performance from a case the same length as a 9mm; and so was born the .40 caliber Short & Weak.
