This lets me air a thought that I've been kicking around .
The Dredd Scott decision by the Supreme court ruled that Blacks could not be citizens since that would allow them all the rights and protections of the Constitution, such as carrying arms when and where they chose.
The decision that Blacks were not citizens was overturned later, however, the underlying premise is still valid .
The Rights and protections of the Constitution are reserved for citizens and are not automatically applicable to non citizens .
Illegal aliens are not eligible, neither are foreign terrorists , they may be kidnapped, killed, or tortured with impunity while still applying the laws in the case of citizens.
That only works if you believe the Rights were granted by the Constitution, not just protected by it.
If they were not granted by the Constitution, but by Nature's God, then every living person possesses those right.
Now the case made easily be made that those who disregard those same Rights of others have also abandoned their claim to them.
Further, I don't believe a trial is mandatory for determining who has violated those Rights in others. The trial will just prevent misuse by those in power.
The 2A could be stricken from the Bill of Rights without diminishing that right in the slightest. It might even help, since there would be no confusion caused by quirky comma placement and a collective interpretation.
With the 9th Amendments in place, the Right to Keep and Bear Arms is still held by the people.
9th Amendment
The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.
