Not as percentage, but in number of fatalies (from your link):
4. Law enforcement workers
Number of victims: 144
Most common manner of death: 38 were highway-related and 33 were homicides
Yep in numbers of total law enforcement. Doesn’t change the accuracy of my statement that being a cop is safer than many other jobs.
Number 4 on the raw number list and nowhere on the fatality rate (deaths/100,000) list. That means there are a butt-load of cops--yet another problem.
