Do you think it's time for the u.s. to ban all guns?:
You know, one of the first things the Nazis did in coming to power was to ban the private possession of firearms.  There's a reason; when they wanted to knock the door down and carry people away without due process of law, they didn't want anyone to be able to fight back.  

It is also true that when guns are outlawed, only outlaws will have guns.  Now, some would say no, outlaws and cops.  I argue that at that point, those two groups become indistinguishable.  Do you honestly believe that every cop in your town is honorable and trustworthy?
