Start a municipal and state watch list like Hawaii has done.  After all, the Anchorage municipality has red flagged inebriates' IDs.  Inebriates can't outright buy booze.  The court system is the only entity that can red flag IDs.  It's time to red flag people that are charged with unlawfully killing another person, pointing or shooting at another person or at a police officer.  Long overdue to bring the gun violence and gun culture mentality to an end.
