"A gun is a tool for killing. Unless it is used incorrectly, it always destroys or hurts or kills."

Sorry, that's wrong to the point of absurdity. None of the guns I've owned have ever killed or hurt anyone, and I'm pretty sure I've always used them correctly.

"The U.S.' obsession with firearms is utterly beyond me"

The European obsession with government control is utterly beyond me. Governments with too much power have killed far more people than privately owned firearms ever have.
