Yeah.. you are wrong on this one... sorry but what he is describing is not two quick draw guys going at it.. one drawn and waiting for the other to draw. Its much more a real life scenario in which the officer has to make a decision: that she is moving, moving in a threatening way, and what she is holding is a firearm, and not her cell phone, or ID or another such thing that one might pull out of their clothing, AND the officer has to maintain complete focus for 5 minutes.
Here is a video about action vs reaction. It takes about .2 seconds for the person to draw and fire as if they intend to shoot a cop.
Then they have the shooter react to a sound. He takes 4-2x as long to react.

Yes, in the premise of dangers to officers. Yes, officers are always at great risk and more than most figure. No, there was nothing scientific about it - other than about himself.
No, you are mis-interpreting what he is demonstrating. He had already done the mental processing and he measured time AFTER this for the cop-killer. The time for the cop to react and act included the officer's mental processing, muscle command nerve travel and then muscles doing their thing. He also is measuring different arm movements. Finally, it more confirms my point as the officer is reacting to sound - which is little different and even less mentally complex than reacting sight. A person - if focused - can react a tiny bit slightly faster to sound than sight.
In the scenarios I told of, my wife is the cop killer. The delay of that officer in the "scientific" video is demonstrating what I posted about - the delay in mental processing and then muscle command nerve signals and finally the muscles reacting to it. That is the insurmountable delay and why she would always "win." She learned long ago in high speed mind/body precision in her athletics she is not mentally telling her body what to do now, but what to do in the immediate future. What that video shows Is the inherent delay reaction time. He actually isn't very fast. Certainly faster than me but I'm average if that nor practice being fast anyway. BUT by his video, the cop-killer has a good .2ish seconds before the cop can even begin to react - at best. My wife was in the cop-killer role. It is literally impossible, mentally and physiologically to act instantly.
My wife is not magic. It is not THAT rare that there are people who could draw and fire before the average shooter could react due to inherent reaction delays of the human mind and physiology. The lesson to cops? If the person is skilled and is going to shoot, by the time the officer sees the gun its too late. Even if not, and the officer does hit the person, it will be so close the person will have got his/her shot off at the officer too.
And, of course, unlike the situation with my wife, police really don't know what's going to happen. Plus the officer is having to mentally process a huge collection of information and what-ifs - where if someone is focused singularly on shooting the officer that person is far more specific-action focused.
Your video, if it proves anything, proves my point. The same principle of inherent physiological/mental delay applies in fighting. That's why fighters have to take a stance to protect against sucker punches by a blocking stance, as it is very unlikely they could reposition fast enough to avoid it. The overall reaction delays for mental processing and then actual muscle movement is quite slow.
The mistake you are making it thinking if the officer only was directly pointing at the person, finger on the trigger, than he can instantaneous fire. But it is impossible. The same mental processing, signals to muscles and muscle delay time applies. And there is no way around it either.
