The 2nd amendment enshrines the right of citizens to own ANY weapon that the police have.
If a SWAT team can carry AR-15’s then so can I. It is my GOD GIVEN RIGHT!
During the 1700’s, the Continental Army carried musket guns that were ALSO available to citizens. A farmer had the SAME firepower as the soldier, and hereby citizens members of the unorganized militia, to this day.
That the military has. They warned about keeping ‘standing armies’ around.
Citizens had and used cannons.
SCOTUS has also ruled that weapons in common use cannot be banned by anyone.
