There is NO reason for guns in civilian hands.

There absolutely is. The second amendment to the US Constitution exists for a very specific reason. Read the US Declaration of Independence. Given, we don't have an insane monarch trying to extract fealty from halfway around the world now, but just because the reason doesn't exist in the wild now doesn't mean that no reason exists at all. Things change, often for the worse. Examine the war-mongering civil-liberties-impairing idiot we have in office now. And then look at his approval ratings. Then tell me that it couldn't get worse.

Is there a tolerable level of violence? No. But sometimes intolerable things must be done.

Edit: Note that I am in favor of gun control (at least in theory) and think that the NRA adminstration is comprised largely of pandering gun nuts. So I'm not coming from that viewpoint. It's just that your statement is a little beyond the pale.
