You can pass all the "make it harder" legislation and sign it into law that you want to. If law enforcement, the school system, the justice system and the medical/mental healthcare system don't do their part and enter the necessary information into the system it will never do a thing. Most of these individuals passed the background check, because their mental health evaluations and any other red flags went unreported. This has to stop. Juveniles can no longer be treated like they are now. You have a record as a juvenile, it needs to be part of your permanent record. And you should have to go through the justice system and mental health system to change it. This not reporting due to their age has to end. Period. And the age for everything needs to be raised, including voting. If we don't view them as mature enough emotionally and/or mentally to own a firearm, then they are not mature enough for everything else. Exceptions would be granted for military service, provided they keep a clean record and aren't discharged dishonorably or with a Bad Conduct.
