It would not be commonly necessary in an otherwise lawful society to need tanks and missiles.
But then neither would rifles and handguns, except for hunting.
And that changes the need for any "military" weapons drastically. They are not designed for hunting, but for random mass killing or maiming humans. Which is exactly what is happening on our streets and in schools.
We almost entered into a war with Cuba and Russia for installing "defensive missiles" in Cuba.
Why would we need to buy "Assault Rifles" for defensive purposes, scaring others into also buying AR15s ?
This is a clear example of going down a slippery slope .
Somebody is being disingenius about this self-defense argument. We already have "well regulated" militias in every state. They are called the National Guard or State Militia. Who is required to register with the State Militia in order to qualify for service when called?
I live in Idaho and everyone has a gun, because in NO.Idaho we run across grizzly bears and wolves and cougars as possible adversaries, but hunting for big game such as Elk and Moose with an AR15 would only needlessly wound the animal without killing it.
I lived there and can testify to that, and a .223 caliber AR15 would not stop a grizzly, regardless of how many bullets you pump into its hide, but a single well aimed 30-06 would.
And obtaining a hunting license without being able to prove you can shoot "straight" should also be forbidden.
And coming back to cars, seatbelts have saved thousands of lives, but should school children be forced to wear bullet proof vests in order to attend school?
