Well, 9/10 times that someone has a machine gun in their home, they are a gang banger or a drug dealer. Does that mean the feds can seize any machine gun they find, without bothering to establish that the person is unlawfully in possession of it?
I doubt you’ll carry your logic to the point of saying “Viva la war on guns!”.
I wouldn't be surprised. Most drug war advocates have no problem with the BATFags taking away scary guns, justified or not.
