Such as?
Some of his nonsense. He shouldn't have drawn his weapon but could have waited for a better opportunity. Doesn't he think they would have disarmed him if he didn't draw his weapon? Second was the Monday mourning quarterbacking that he could have drawn his weapon faster and would be better off with a dot sight. Yes, in a ideal world he should have had his weapon in his hand when those shady characters came into the shop but it's not 1825 any more. A bad guy doesn't worry about the law but a man legal with a hand gun has to be concerned with legal ramifications. A dot sight for under five yards? You shouldn't need any sights for a five yard shot. If you have any training you can hit a man sized target at 5 yards without sights 100% of the time. Yes, I realize when the target is moving and the good guy is moving it changes the dynamics along with the adrenaline. In my mind the guard won is the bottom line. He survived the fight. I have zero love for guys that Monday morning quarterback videos what they would have done. Learn from them but to make yourself a hero by saying what you would have done is bs. Yes, hindsight is 20/20. Guys that are good target shots hitting stationary targets are not combat trained. One good drill I have been part of is running 200 yards then shooting to stimulate stress. It changes a lot of things regarding hitting a target. Practicing quick draws under a stop watch is good training but to think you are having going to have a quick draw with a bad guy without seeing his gun produced is nonsense.
I have been carrying for over 40 years and I continue to carry with intensive extensive training. Ever use a FATS training system used by Federal law enforcement, military police and some bigger Police departments? It's a shoot don't shoot system. It shows how most can make a wrong decision to shoot under stress and unknowing situations. That's why I say practicing quick draws under time is a good thing but it can also lead to bad decisions. I love when they put reporters on the FATS system to see they shoot good guys over 50% of the time. If you're unfamiliar with the system an instructor will say something like you have a call of an armed robbery in progress. You face the screen and you walk into the store. A black guy who has his back to you whips around suddenly. Turns out he's holding a cell phone in his hand saying the shooter is in the back. So many will quick draw to shoot him. Then you see a person on the ground in blood with a good Samaritan assisting. As you get closer the good Samaritan turns and shoots you. The various scenarios continue.
A good guy with a gun has fractional seconds to make a sound decision but a judge, jury, press and the public will Monday morning quarterback for days and months thinking what they would have done.
