However, if I recall the consitutional rights do not apply to foreign nationals, as they are not US citizens. If war was ever offically declared, they would be foreign combatants.
Absolutely wrong. Except for certain political rights like the qualifications to be an "elector" (voter) and to hold certain offices,
all of the civil rights guaranteed in the Constitution apply to any person legally and physically present in the USA.
This means foreign nationals on visas, or those who have green cards (i.e. permanent residents), etc.
You're correct that this can change in a declared war, but that need not concern us here.
Even illegal aliens have the right to due process, to be protected against cruel and ususual punishments, etc.
Resident aliens with green cards can buy guns and in most shall issue states they can obtain CHL's.
In open carry states they can open carry if they want to.
And if you had no background checks to buy guns, as many here believe is an "infringement"
who would know whether someone was an illegal alien, a resident alien, a convicted violent felon, a child molester, a member of Al Qaeda, or a law-abiding native-born American? You walk into a store, pick out the gun, an MP-5 of course, grab some extra mags, some duct tape (to jungle rig the mags of course) and a few cases of ammo, put your money down on the counter and you're on your way to die gloriously in the service of Allah, right?
This is what happens when people don't think through the consequences of their cherished, if simplistic, notions.
I'm still waiting to see what you had in mind and your argument. How can I determine if it's "reasonable" if you refuse to explain and/or detail your rationale?
I can't blame you for not wading through this whole tedious thread. But I've posted my position as to what is "reasonable" and hence not an "infringement" a couple of times. I'll summarize.
1) Background checks should be required to purchase.
2) No violent felons, children, adjucated mental incompetents, or adjudicated drunks/drug addicts allowed to purchase.
3) No license required to purchase, possess or transport non-NFA firearms. No license required to possess firearms on one's own property. Shall issue license required to carry loaded firearms in public. Either concealed or open is OK.
4) Full LTC reciprocity among all states and political subdivisions thereof.
5) Concealed carry by licensees allowed in any workplace or public accommodation, with certain exceptions. A government agency or private property owner could set up a "sterile area" where carrying is banned, but they would have to provide gun check lockers and would be required to screen everyone entering for weapons. Certain places such as airliners, courtrooms, etc. would be defined as sterile areas by law.
6) No registration of firearms allowed.
7) Special license required to purchase or possess full auto weapons, SBR's, destructive devices, and sawed off shotguns. Carrying full autos, SBR's, destructive devices, or sawed off shotguns in public could be banned. (Similar to NFA provisions.)
The above is just off the top of my head. I wouldn't bother nitpicking at details. I prefer to think in terms of the big picture. The single theme linking all of the above proposals is that they place little burden on LAC's who choose to possess or carry guns, while putting a larger burden upon criminals, terrorists, etc. who might elect to do so.
In this way, the balance of power between LAC's and criminals, terrorists, etc. is shifted in a favorable direction (i.e. towards the LAC's).
The fact remains that if anyone can buy any gun with no questions asked, and carry it anywhere they choose with no questions asked,
you would have Al Qaeda death squads armed with MP-5's running suicide ops on airliners every day.
It would simply be too easy for them not to do it.
And the people who say, "Well, let them try because the good guys would have MP-5's too." are clearly way, way up in some very tall tree.
Full auto firefights at 35,000 feet are simply not an acceptable consequence of someone's interpretation of the Second Amendment.
No legislature would ever pass laws (no background checks to purchase, open carry anywhere, no questions asked) that would facilitate such a thing.
No court would ever overturn laws (background check requirements, licenses to carry, ban on carrying on airliners, in courtrooms, etc.) that would prevent such a thing.
And make no mistake, our current laws do make this type of attack unfeasible. How do we know? Simple. AQ has never attempted it. Whereas if we had no "restrictions", it would be a simple matter, as I stated above, for them to run ops like that
every day.
