Whenever anyone tells you they don't know the exact "interpretation" or "meaning" of the 2nd Amendment, or try to make you believe they don't understand it, there are only a few possible reasons. One, is they are lying, and want to make the majority of Americans believe the 2nd amendment says something which it clearly does not. The other reason, is public education has allowed a revisionism of how law is to be made. Nowdays, people beleive the Supreme Court can dictate law, and the law is to be made by the Legislative branch, all of which must be "in pursuance of" the Constitution, or it is not law on it's face. You do not need a Supreme Court decision to determine if a law is passed that "infringes" upon your right to keep and bear arms, then that law which bars yor bearing arms, is dictated by the Constitution itself, as not lawful.
Many attempts are made in order to try and make us believe we are ignorant of the meaning, of a simple sentence. You don't have to be a "Constituttional Scholar" to understand this Amendment.
Keep in mind, the 2nd Amendment is a sentence consisting of a total of 27 words, and we are taught the meaning of those words previous to even entering high school.
The school system, and the legal system, simply do not want you to read all of those words in the same sentence, since it would possibly lead to students reading all the others in the Bill of Rights, and reading the Articles of the Constitution, which would really be a problem for the governmental system we have unfortunately allowed to usurp our original system of government. We used to be a "Representative Republican form of Government" with control over all three governmental branches, including the Judicial. Now, the Judicial controls us illegally, according to the Constitution's VIth Amendment, because all trials are to be public, by jury.
No plea bargains were ever allowed under the Constitution. By allowing Judges and D.A.'s to begin deciding sentences, we gave up our right to control the Judiciary, thus the stupid idiotic "case law" we see allowing all sorts of onerous governmental regulations and control of your life.
I'm surprised they don't tell us in which cadence to breath in and out.
