Police in Charlotte, North Carolina, are set to become guinea pigs for a new high-tech approach to improving relations between cops and citizens. The Charlotte-Mecklenburg police department is working with University of Chicago researchers to create software that tries to predict when an officer is likely to have a bad interaction with someone. The claim is that it will be able to forewarn against everything from impolite traffic stops to fatal shootings.
FiveThirtyEight’s look at the program points out that previous efforts to use algorithms to nudge police to do their jobs better haven’t worked out. Chicago’s police department gave up on a system introduced in the 1990s after resistance from cops who didn’t like working under its algorithmic eye.
As well as concerns about trust and retaliation, one problem with that system was its poor accuracy. Although predictive algorithms have improved in the years since, that will still be a major challenge.
Training software to make accurate predictions requires a lot of data. Computing companies such as Google and Facebook have data points by the billion lying around, and large data sets have been a crucial part of recent advances in artificial intelligence.
But the data needed to create software that can accurately guess at an individual cop’s future actions is surely much scarcer. And accuracy is very important here. If Amazon recommends two movies and you only like one of them, you probably won’t feel slighted and misunderstood. If an algorithm starts offering tips on how to do your job—and your job involves navigating potentially life-threatening scenarios—it had better have good advice.
