Sure, dealing with public/people in general and day to day is something anyone should be able to do. The skill-specific part of LE, is handling the unusual and potentially dangerous situations , and the split-second changes that can occur, while preserving your life first, then the life of the suspect as best as reasonably possible.
I don't know which police department you train with for your use of force training, but the training isn't to use deadly force whenever and wherever, but to use it when necessary. And that's entirely subjective. Sometimes use of force starts at deadly, sometimes it starts at less-lethal. It depends on the totality of the circumstances.
We medevac'd a BP agent a few months back who was solo out in the field like they all operate....middle of the desert. Barely alive. Came across a group of illegals, one of whom was a felon with numerous warrants out for his arrest. A surveillance camera out in the field caught video of the fight in progress when the felon resisted arrest, the surveillance video feeding back to the station. This guy kept attempting less-lethal force....mace and baton...against an unarmed felon who was bigger than him and beating on him, eventually with a large rock. Bashed the agents head in, broke both eye sockets and left him for dead in the desert before responding units could arrive. Deadly force should've been used long ago, but we think the newer agent was afraid to use it against an "unarmed" individual until it was too late for him.
That felon should've been dead 1 minute into the 10+ minute physical fight.
Not everything is as black and white as you'd like to make it CC. And yes, dealing with when things goes wrong DOES require brains and technical training.
