So what did they mean when they mentioned a well regulated militia?
If you don't know how to answer that, then go ahead and dodge the question.
The People have a right to keep and bear (carry on their persons anywhere) arms.
A well regulated (ready and equipped) militia (a non-standing army made up of the People) being necessary (in the eyes of the Framers) to ensure a free state (not a "state" like New Jersey) requires that the People be armed and ready to serve at all times. Weaponry wasn't to be held and distributed by the Government.
Why anyone with average intelligence can't parse this sentence logically is beyond comprehension.
