Here is a training film made by the CHP that goes into great detail about the Newhall Incident. Even has a tape of Twinning telling a reporter that he will kill himself before he goes back to prison. http://www.mefeedia.com/watch/27581823
On the Miami Shootout. The agents had body armor but not sufficient to stop 5.56 bullets only handgun ammo. Wouldn't have helped them. Mireles didn't really kill Platt, he was already dead from the shot Dove had delivered earlier in the fight. He just didn't know it yet. Matix fired one shot and was out of the fight from the beginning. As Mireles said in a statement he made later. He had heard a lot of BGs say they would never be taken alive but 99.9% of them were full of it and gave up when confronted. This time they didn't. Maybe that was part of the mindset. Best book on Miami Shoout is by a Dr. Anderson French. I have read it and it is very detailed.
