but for argument sake...it would take ATF most likely 5 years to even begin to figure who has what. it would be like prohibition all over again. so most would simply "hide" what they have and wait for the next round of elections or what not. imagine the HUGE new branch of ATF just to retrieve said weapons. we all know the FBI would be incompetent.
we would demand they round up illegal owners of weapons first....but how you ask...exactly they could not.
shamefully the poor guy that gets broken into and dispatches the bad guy would be in prison for failing to turn in his firearm
cross bow sales will skyrocket
