You might not know it from watching TV news, but FBI statistics show that crime in the U.S.—including violent crime—has been trending steadily downward for years, falling 19% between 1987 and 2011. The job of being a police officer has become safer too, as the number of police killed by gunfire plunged to 33 last year, down 50% from 2012, to its lowest level since, wait for it, 1887, a time when the population was 75% lower than it is today.
So why are we seeing an ever increasing militarization of policing across the country?
Given the good news on crime, what are we to make of a report by the Justice Policy Institute, a not-for-profit justice reform group, showing that state and local spending on police has soared from $40 billion in 1982 to more than $100 billion in 2012.
