Excerpt from “Confessions of a former bastard cop” at http://medium.com/
…well over 90% of the calls for service I handled were reactive, showing up well after a crime had taken place. We would arrive, take a statement, collect evidence (if any), file the report, and onto the next caper. Most “active” crimes we stopped were someone harmless possessing or selling a small amount of drugs. Very, very rarely would we stop something dangerous in progress or stop something from happening entirely. The closest we could usually get was seeing someone running away from the scene of a crime, but the damage was still done.
And consider this: my job as a police officer required me to be a marriage counselor, a mental health crisis professional, a conflict negotiator, a social worker, a child advocate, a traffic safety expert, a sexual assault specialist, and, every once in a while, a public safety officer authorized to use force, all after only a 1000 hours of training at a police academy. Does the person we send to catch a robber also need to be the person we send to interview a rape victim or document a fender bender? Should one profession be expected to do all that important community care (with very little training) all at the same time?
To put this another way: I made double the salary most social workers made to do a fraction of what they could do to mitigate the causes of crimes and desperation. I can count very few times my monopoly on state violence actually made our citizens safer, and even then, it’s hard to say better-funded social safety nets and dozens of other community care specialists wouldn’t have prevented a problem before it started.
