Sure. Stories are important. It's really not all that common, though, if we're being honest. According to this random memorial page[1] 48 police officers were killed in the line of duty last year in the US, an annual fatality rate of 0.006% assuming 800,000 active officers.
The numbers aren’t that low for lack of trying, though. The majority of attempts fail because the police are better-equipped and better-trained than the people trying to kill them. That’s part of why there are so many officer-involved shootings in the first place.
