I have a hard time believe anything else your article says after it implies Adam Lanza was able to legally purchase fire arms as a mentally ill person. He murdered his mother and then stole her fire arms for the shooting.
These lists have affected innocent people in the past, including many veterans who are told they are simply unable to own a gun, because of some list they have never heard of. It’s the same reason many people oppose banning guns for people on the no fly list. The list has several U.S senators on, and even children, proving them to be very inaccurate.
From your article.
“The National Rifle Association, gun advocates, and civil rights advocates, including the ACLU, argued that the rule would strip Second Amendment rights from beneficiaries without due process.”
This seems reasonable in my book.
