I'm confused by this argument; how does predictive policing relate to measuring department performance? The biggest concern I can see is that putting more police in certain neighborhoods will bias the input data for those models (presumably police reports), but this doesn't seem to be what this section of the article is saying. It also doesn't seem like a good reason to avoid computer models, but rather to increase transparency.

A predictive policy generally implies an expected outcome, such as: in an area with this kind of demographic, income level, history, etc, etc., we should expect to see X number of drug and weapon possession offenders. If a precinct ends up arresting significantly fewer people for these offenses, then it can be interpreted that the precinct is underpeforming when it comes to patrolling and finding probable cause to stop and search. I referenced Adrian Schoolcraft in another comment, but here's another retelling of his situation: http://www.thisamericanlife.org/radio-archives/episode/414/transcript http://www.thisamericanlife.org/radio-archives/episode/414/t... Ira Glass: The atmosphere at the 81st precinct was set by its commander, Stephen Mauriello. When Mauriello showed up, Adrian Schoolcraft says, things changed. Offices were told to write more tickets, do more stop-and-frisks, arrest more people for low level offenses that they might otherwise let go-- get their numbers up. Adrian Schoolcraft The pressure definitely increased when he arrived and took over as the commanding officer. The analogy I would uses is like having a boot to the back of your heel. It is do this or else. The rent's due. Ira Glass The rent's due? Adrian Schoolcraft The rent is due. Pay the rent. Did you pay the rent last month? Ira Glass Pay the rent means did you get your numbers? Adrian Schoolcraft Correct.
