One of the most significant developments in the history of policing is the use of statistics to track crime patterns and to determine how to react to them. New York City’s CompStat program has served as a model not just for cities around the United States, but also globally. And it makes sense, right? The better we track crimes and the more data we have, the more effectively we can allocate resources to improve public safety.
Unfortunately, New York City (and everyone else) has found that it isn’t that simple. Jack Maple’s bold vision for a statistics-based police department has been plagued by inconsistent application and perverse incentives that prioritize numbers over public safety. The perpetual conflict between good policing and good CompStat numbers has mitigated the program’s positive effects and magnified its criticism on civil rights grounds.
CompStat reinforces our biggest problem with statistics in public life: the numbers we increasingly depend on don’t lie, but we don’t always know which truth they’re telling us.

![Life In Prison For Your Name
When Joyce Ann Brown saw her name in the newspaper in connection with a gruesome murder, she went straight to the police to clear up the obvious error. She was at work when it happened and she had no violent criminal history. How could the police possibly think she could be involved?
The moment police found out the getaway car was registered to Joyce Ann Brown a different person with the exact same name the coincidences began to mount. Along with incorrect witness identification, too much reliance on familiar analytical patterns, and a lying cellmate, just a year later Joyce was serving a life sentence in a Texas penitentiary.
Most everyone else would’ve accepted their fate. Joyce kept fighting. And thanks to a dogged media who refused to believe the district attorney’s narrative and an organization dedicated to helping the wrongfully-convicted, Joyce was able to walk free.
Sally Clark fell victim to probability errors. Brandon Mayfield’s injustice was about cognitive biases. Joyce Ann Brown’s life was turned upside down by a series of strange coincidences and bad prosecutorial judgment and we just keep making all of the same mistakes.
