The arrest of an Uber driver in connection with a shooting spree in Kalamazoo, Michigan last weekend has brought renewed focus to the rigor with which rideshare companies conduct background checks of their drivers. State and local governments have been looking at the background check issue in a number of ways as part of rideshare-related legislation over the past year. Here’s a primer.

In 2008, two North Carolina college students from two the state’s flagship universities were murdered. The alleged murderers were no strangers to the criminal justice system. But because of the fragmentation of information in the state’s criminal justice system, it was hard to connect the dots on the alleged murderers. Department of Correction cases are identified by an identification number, the sex offender registry uses separate identification numbers and court cases have yet another number.  North Carolina made the best of a bad situation. The murders led legislators to order the creation of an integrated data system. The result was the Criminal Justice Law Enforcement Automated Data Services program—CJLEADS—an Innovations award winner for the Southern region.
