I'm curious if anyone has a data source on this that actually breaks down by duties? A "police officer" can be a beat cop in Baltimore, or a desk sergeant in Omaha, or an IA reviewer etc.

When people say "being a police officer" is risky they obviously mean the part where you go around physically enforcing law and order, not the other parts that are actually the majority of many long-term police careers. But the fact that the current beat cop will in 5 years have a much safer job doesn't mean that the current job is not very risky.
