So can privacy rights. So can property ownership. The wrong words can lead people to suicide. Bad ideas can lead people like Timothy McVeigh to kill hundreds. Religion has led people to kill abortion doctors.
Privacy rights allow people to break the law without anyone knowing it.
Property can be used to train killers. No constitutional right should be qualified before use. No government has the right to arbitrarily place restrictions and qualifiers on any constitutional guarantee, Second Amendment or otherwise. And you don't have to have a Harvard law degree to know that gun rights are being treated far more strictly than every other right in our Constitution.
