I think differently.
Re-holstering is not the least bit dangerous if you prepare ahead of time by wearing the proper clothing, the right equipment and have enough training. It just takes attention to detail BEFORE you put the gun on and practice. It is muscle memory like everything else.
Civilians / cops doesn't matter, nobody will ever have perfect situational awareness and should be aware of potential threats or threats that don't immediately look like threats. Just because you stop shooting doesn't mean the shooting is over or there are no more threats. After just experiencing a lethal force encounter, you need to assume a retention stance, open up your field of vision and when that is over and no possible threats are seen take the last step and holster your weapon while maintaining vigilance by keeping your eyes on the situation.
You should have enough training and confidence to holster your weapon without taking your eyes off of the surrounding situation because if you just used your weapon there is a good chance you need both your hands to pick up your kid(s) and leave or render medical aid to a victim of violent crime or holster so you don't get shot by responding police or another bystander.
Train until you can do that effectively so it is second nature and then train some more and it doesn't cost anything and you can do it at home.
