The confiscation thing is just an add on. If your separated from a lunatic, and she gets a restraining order on you, when they come to round up your weapons, if there is an assault rifle, they will charge you for not turning it in, and proclaim that the law is working.

From my experiences, your average local, state, county and federal officers couldn't tell a hi-cap mag from a slap mag.
