If it's a background check, it's a background check. Otherwise it's "mandatory registration in the government's database", not a background check.

There's a difference between retaining the fingerprints of convicted criminals as part of their case file and pre-emptively collecting fingerprints on people who are not even suspected of a crime.

If there's anything less than a 0% false-positive rate, having a massive database of fingerprints to scan without any criterion will just make it more likely that the police will show up at your door because "your prints were found at the scene" of some crime.
