Regulation is essential to the 2nd Amendment's purpose

Background checks, training, and permits all seem reasonable for a well regulated militia as opposed to any yahoo who wants a gun.

"Well Regulated" does not just mean well equipped. It also means well trained, well disciplined and with a lawful chain of command.

The government can and should regulate what type of weapons are permitted. That is reasonable.

The government can and should regulate who is legally prohibited and enact regulations that prevent them from obtaining firearms. That is reasonable.

If the "militia" is not well trained, it is nothing more than a danger to itself, our nation and its citizens. This should be blindingly obvious.

If there is not a lawful chain of command, the so-called militia is just an armed mob, a dangerous pack of vigilantes, or an angry nut with a grudge.
