But that is part of my point. In your scenario, the kid could obtain the gun legally, but he didn't. Tightening the laws won't make any difference, because he wasn't following the ones that were already in existence.<quoted text>Illegally is a broad term (giving a rifle to a kid under 18 is illegal, but if he does not go wonky till after 18, was the gun obtained illegally, even though at present he could legally posses the weapon).
A better stat would be how many lawful gun owners (crazies not included), actually commit a homicide with their weapon.
People are more impressed by big numbers and I suspect that the majority of gun homicides are committed by guns that were obtained illegally. Most of the murders aren't mass homicides, they are single or double homicides that don't attract as much attention, especially when they occur in urban areas. From reading the articles in the paper, most of those murders aren't committed using "assault" weapons.
I would like to have educated conversations on this topic, especially among my political associates. My opinion is that our focus needs to be on mental health and on the values that we are teaching our children (words and actions as a society), but I need to be able to back up my discussions with numbers explaining why empty legislation is not the solution.
