No, that was not the podcast. I remember that show, Chuck was talking cognitive ability, and how people process the information. The show I listened to, the instructor was more talking about shooting to fast from a legal stand point. It came down to shooting the bad guy in the back, if they turned and tried to end the fight. If you are pulling the trigger with out evaluating the scene, you will not "see" the bad guy turn, and an aggressive prosecutor will use that against you. I'm going to go back and try and find it, it was from less then 2 weeks ago
This was discussed in depth at a MAG20 I attended recently, put on by Massad Ayoob. Also, the Force Science Institute discusses in detail human reaction time to expected and unexpected stimulus. The bottom line is even with 1 shot, you can be facing an assailant and decide to fire, while at the almost exact same instant they could turn to flee, and your 1 shot could stroke rear of the centerline of the body. Resulting a "he shot him in the back" kneejerk reaction. Science and expert witnesses can speak to this on the stand. Just hope you never have need of such testimony.
