From The Quad-City Times:

Anyone conversant with the English language would recognize this as the rationale for not infringing the right of the people to keep and bear arms.
With the rationale gone — states now maintain a National Guard for which weapons are supplied — it would seem the ground on which the amendment stands has caved. I’m surprised the Supreme Court’s “originalists” haven’t noticed this. They might also examine the argument for the amendment in the first place.
