It's a case of a measure ceasing to be a good measure because it became a target.
The purpose of running a background check is to predict if someone will be a problem. But they work by measuring interactions with the legal system (probably convictions in particular?). And if suddenly most of the behavior you care about stops generating records of interactions, well background checks just got a loss less useful.
