The fallacy is in the president’s very language. “…‘Common sense’ in laws that allow citizens to own guns…” The constitution does not speak of gun ownership as something the government has the power to “allow”. The constitution protects the right of citizens to own firearms, a right antecedent to government.attn.com/stories/8813/president-obama-addresses-gun-control?utm_source=beingliberal&utm_medium=fbpost&utm_campaign=influencer
Obama said that the U.S. needs “common sense” gun laws that allow citizens to own guns but also prevent the wrong people from getting access to them. He said that the only way to reach that balance is to have better conversations about gun laws that don’t result in arguments about the “destruction of the Second Amendment.”
So, the goal then is to prevent those who shouldn’t own guns (criminals, non-citizens, etc) and those who lack a mental capacity to own a firearm, from buying one. And great care must be taken regarding the latter because we must have an overwhelming reason to restrict a right the constitution says shall not be infringed.
To the extent that the NICS system can do that in conjunction with adjudication, it is a good idea. Beyond that, it can be used in a subversive way, such as recent attavks through the VA and Social security.
