Given that there are more than 900,000 sworn officers, and with 128 fatalities (including accidents) reported in 2017, that brings the fatality rate to under 15 per 100,000. In other words, a job in "grounds maintenance" is more risky than being a police officer.
Dealing with violent crime constitutes only a small minority of what police deal with on a daily basis. For example, in 2014, out of 11,205,833 arrests made nationwide (in the US), 498,666 arrests were for violent crimes and 1,553,980 arrests were for property crime.
That means 82 percent of arrests were made for something other than violent crime or property crime.
Moreover, many of these non-violent offenses — such as drug use, liquor violations, carrying an illegal knife, or other infractions that should be regarded as small-time offenses can result in serious jail time or prison time, as well as steep fines and lost earnings.
