It seems like people who argue in favor of stricter gun control in the US hinge a lot of their rhetoric on the idea because the constitution was written a long time ago the whole thing most have stayed the same.

As I understand, in addition to the process of actually amending the constitution, the Supreme Court is able to reinterpret it within the current context to keep legislation around it up to date.

As recently as 2008, the Court found that the 2nd amendment guarantees an individuals right to keep and bear arms outside of the context of a militia, doesn’t this show that the constitution and 2nd amendment are being scrutinized/kept up to date?

Other than entirely amending the constitution (which there is a framework for, and is entirely possible) how else should the constitution be modernized?
