With due respect to gun lovers, I always find it strange when they bring knives on the table for discussion. Guns and knives are apples and oranges. Like Rethink said above, guns are designed to kill. The only purpose of gun is to kill. Knives have so many uses in everyday life. :) But one thing is true. People are getting more psycho everyday. Our thoughts are getting more and more violent. That is why it is best to let go, try to focus on the good things in life. One less violent thought out there, one less burden for life.
