I don't really want to get into the actual meat of the argument, but please use per-capita death stats so the numbers are actually comparable.

Here's the same logic applied elsewhere:
It's not dangerous to be a black man in America. What's really dangerous is to be a El Salvadoran living in El Salvador(the country with the highest murder rate in the world).
Police officers are volunteers, not conscripts. They're free at any time to choose a less dangerous profession if they so wish.
Ultimately it doesn't matter if policing was more dangerous than working in an asbestos-uranium mine on a fault line. There's no excuse for law enforcement to be breaking laws without consequence. People who can't tolerate the risks should go do something else.
