Have better background checks to help reduce weapons from getting into the wrong hands.

Having background checks that include a required photo id, to be present in person rather than online, should require background checks even if the dealer isn't licensed, should be passed in all states, should require background of their medical records, as well as the various other current background checks such as the Firearms and Explosives (ATF) Form 4473. This can help mentally unstable people from getting their hands on weapons. Not only that but it will help reduce the black market sale of guns to criminals.
