When you fill out that ATF paperwork to buy a fire arm, you agree to surrender your fire arm if you are charged with a dv crime (if found innocent you get it back), found to have psychological mental illness, or discharged from the military for anything other than an honorable discharge (i.e. Honorable discharge, honorable medical discharge) any other discharge disqualify' you from ammo and firearm possession. Further gun restrictions would not have prevented these murders, it only would have added to the criminal charges.
