The founders words "well regulated" means "well trained."
However, they never said anyting about getting government permission.
Being properly trained in weapons is one of the responsibilities we as citizens have. It's OUR responsibility to do so, not the government's to mandate.
It's up to us to ensure we are well-trained, and well-regulated. Government cannot, consitutionally, dictate what the training is or even require the training.
The day we have to go to the government to get permission to exercize our second amendment rights is the day we cease being a constitutional republic...
