Then wouldn't that make any sort of capital punishment unconstitutional? Since that definitely infringes on the fundamental right to live?
To say that as a fundamental right there should be no restrictions on gun ownership means you can't prevent felons from owning guns or the mentally impaired or place any age requirements on gun ownership at all. Some restrictions are needed, and must be in place. The question is where the boundary between permitted restrictions and unconstitutional restrictions lies. And unfortunately the court decision does nothing to help identify that boundary.
And we can’t leave that boundary up to common sense because liberals don’t have any and disdain anyone that does.
