This is so on the bullseye. I know several people who carry daily and ever single one thinks when the bullets start flying they will be John Wick and everyone else the generic henchmen. Meanwhile actual evidence shows the most effective strategy when encountering someone with a gun is to run the fuck away. Pulling out your own gun dramatically lowers your chance of survival.
