Definition: "big scary gun with many bullets that go fast"

They try to make definitions as broad as possible to get around the second amendment.

But that doesn't make any sense, since "assault" and "assault with a weapon" are crimes with very specific legal definitions. Under which the weapon used for the "assault with a weapon" crime can be literally any object - a rock, a baseball bat, a revolver... literally anything used to assault someone.

So it's really weird to randomly make up a word "assault weapon", with a much narrower definition than what is meant by a weapon for the crime of assault (which has already been precisely defined).
