The point made here, and in other forums ad nauseum, is that almost any object can be used as a killing instrument.
Well hey, there we go. Taking guns seems just as silly to me as taking cars away seems to you, because I was raised in an environment where guns were part of life. But if I ever get scared of living in the U.S. because of guns, I'll be sure and head for Paris, or whatever the capital of Canada is.
