My ex-brother-in-law killed a family of four while DUI. The cops really screwed up the investigation so he was able to get the charges down to a minor moving violation. He never saw the inside of a jail.
When I was in high school a friend of a friend that I knew and had hung out with at a couple of times was a serial killer/rapist. He was one of the last people executed by that state.
Edit: My grandfather killed some Nazis in WW2. Several former coworkers killed people in the line of duty as soldiers. And, I worked as a records clerk at a nursing home, so I knew several doctors and nurses that had taken people off life support.
Yeah, no. Most members of most militaries haven’t directly killed anyone, even during wartime.
