It’s about 100 officers a year in the U.S. About half are homicides and the other half are car accidents on the job. It doesn’t rank in the top 10 most dangerous jobs (per capita) in the U.S. according to the BLS. The number of deaths will be much higher this year, at least double, due to COVID19 deaths. The job pays well and comes with a pension. It’s nearly impossible to get fired and if you do get fired, most officers get rehired elsewhere.
