Calling AR15s "Assault Rifles" is like calling Sport Utility Vehicles "Assault Vehicles".
I like comparing guns to cars.
If there was attempts at "Car Control", like gun control, they would try to ban all cars that can go over 55mph in stead of setting the speed limit at 55. They would ban SUVs or any car that weighed over 2000 pounds because you could kill A lot of people with those things.
But the police and military could have fast cars and big powerful trucks.
All of this even though they can still build cars elsewhere in the world that can go fast.
--Because no one would dream of violating that law.
