Summary

This study looks at California's Armed and Prohibited Persons System (APPS), which identifies people who bought guns legally but later became banned from owning them. Researchers want to see if the program lowers the risk of future violent crimes and firearm-related arrests. About 20,000 adults who lost their gun rights are being followed to track arrests and emergency mental health visits.
