That is the questions being proposed, and to be honest I am a 2A person, I would like it to mean bare in public for non criminals but that is not the current ruling or historic rulings by the supreme court. As it sets bare means you can pull out your gun and use it as part of a state sanctioned militia (don't really exist anymore) or as the most recent ruling specified, in self defense. What is not "legally" clear is "where". Well it is legally clear, the only place right now you have the right is on your private property, or property you have been given permission to possess a weapon on. In states if you have a CCW or they have other carry laws, you are afforded the privilege of being able to bare in public and common property with some restrictions. Again this is not my definition, this is what they have ruled.
And that is the current arguments being made, as their is the implication that by the preamble about the state needing the people to be armed to supply the militias if needed, that if they were called into the militia they would almost certainly not be baring arms on their property. We also have to take into account history, and historically the government did not strictly control open lands they were considered open lands or communal so pre-1900's carry laws being what they where, generally only applied to entering and leaving town, pretty much everywhere else no one has beef with someone having a gun. Times have changed, federal uninhabited land is shut off from the people for the most part and rights generally don't extend there anymore, as well town is a whole lot bigger now. These are arguments being made in support that the framers actually meant the right was "in public"
It's not a matter of what I think it means, it's a matter of what the supreme court thinks it means. So far they have been a mixed bag, the inherent self defense ruling was good but honestly should have been a no brainer. Given that one of the founding fathers was killed in a dual, and duals up until the 1900's where pretty much considered mutual self defense.
I think the ninth court hosed the decision on the Federal Assault Weapons Ban as this directly affected guns of similar features but different looks one could own or features that could be placed on guns. None of that really bothered me as a Browning BAR 300 win-mag with a modified magazine for high capacity would absolutely dominate the battlefield, but the key there is the precedent because by being able to ban pieces of the gun (because they only recognize the receiver as the legal gun), they have set the path for the current bans on magazine capacity and that is concerning because if it stands based on precedent, the 7 round magazines restriction, can legally be reduced to 1 round magazines, in effect only legalizing single shot weapons and while I know in the movies and video games, everyone dies from the first shot, the reality is a higher percentage of people survive shoutouts than die from them, even after receiving multiple gunshot wounds.
