Not being compelled to risk your life is different than it not being your job to stop/prevent crime.
It may be your job to collect shopping carts in a parking lot, and you may choose to go out in a thunderstorm to get those carts, but no judge is going to compel you to risk your life.
Much like a cop there is a risk of injury doing your job every day, so you can’t just never do the job, but some risks are above what people commonly consider normal. I think almost every example you are aluding to falls into that category and doesn’t preclude them from the job of preventing crime.
