NP5491 - very good questions!  in the human/gun equation, the HUMAN is the more important factor!  everything else is a dependent variable!  but the HUMAN is the more difficult aspect to control - legally - especially in our present-day VERY liberal, PC society.  if we could control the HUMAN, the gun, the tool, would automatically fall into place as a tool, for any reason, (which is what it is - a very efficient and deadly tool)!  every characteristic aspect - the morality, the ethics, the psychology, the emotions, the reasoning (or the lack of) - are all HUMAN TRAITS!  the gun possesses none of these traits!  so how can one place "blame" on the inanimate tool?  what of all the other tools - the hammer, the pick, the knife, the lever, the car, the bicycle, the airplane, the pot, the pillow, etc?  should all those be cast aside as well?  every result - good or bad - totally depends on the HUMAN who uses one of these tools!  now let the logical "discussion" begin.......!
