Crime down, arrests up

A couple weeks ago, I had an interesting conversation with our County Attorney, Joe Kelly. We ran into each other before a meeting at the Malone Community Center, and chatted about his perception that felony prosecutions are up this year. I pulled up the most recent data on my smartphone, and indeed felony arrests by LPD are up about 10% so far in 2016. We speculated about what might be cause of this increase.

Afterwards, I put together a chart of the trend since the turn of the century, and compared it side-by-side with the crime trend. It's rather interesting.




Crime in Lincoln has been falling pretty significantly, whereas felony arrests have been increasing--especially in the last four years. This seems a bit counter-intuitive: I would expect that less crime would mean fewer arrests.

These charts begin in 2000, but the patterns for both crimes and felony arrests are more longstanding. These trends actually start back in in 1991. Interestingly, misdemeanor arrests do not show a similar pattern. They have declined slightly between 2000 and 2015, and are down by more than a third from their 2008 peak. I have a working theory on why felony arrests are increasing, but it's going to require some research to put my guess to the test.
