Liar. The rifles she is referring to are protected by the Second Aamendment. Actual assault rifles are already heavily regulated under the 1986 NFA. So called 'AsSaUlT wEaPoNs' is a made up term used to describe modern semi-automatic firearms that include SKS, AKM, AR15, and even the Winchester Model 100 and Remington Model 750 because they can accept a "HiGh CaPaCiTy MaGaZiNe" if someone were to make one for them.
These are the weapons used in the fewest firefarm homicides per annum.
They are absolutely protected by the Second Amendment and, according to Heller, are precisely the kind of that are protected.
You're either lying or plain ignorant.
