Coming from a country with strict gun control as well - I have to say that I've never understood the American love affair with guns. Guns don't kill - but any lunatic can get a gun - and that is the problem - lunatics with guns! Sometimes I think that the line between responsible and irresponsible ownership in terms of guns is lost in the political argument. And gun ownership should be a responsibility - and should not be a universal right.
I'm also with TYWD on the death penalty - it serves no purpose except revenge. Heck, if the death penalty were a deterrent there would likely be far fewer mass murders in the US. The media should certainly stop sensationalizing mas murder as well - all that does is bring out one more unhinged copy-cat killing.
