This is the most astounding stat for me:
So 67 % of all murders in the US are carried out by firearms.
Of those 12,000 + in the US in 2011, maybe only a single digit number were victims of a school shooting.
So Yes banning the sale of Assault Rifles, and restricting the sale of guns even further isn't going to stop all of these high school shootings, but you have to accept that the ease of availability of guns is contributing to the crime figures in the US.
Its sad isn't it. Everybody has their own theory, and most of them revolve around something that is available all over the world. Just like COD, just like Marilyn Manson Music, Just like Quentin Tarrantino movies, yet the problem with gun deaths is exclusively an american problem.

This is somewhat interesting, murder's accounted for 0.7% of all deaths in america in 2009, and it was down 0.6% on the year before, murders in 2009, 16k roughly, suicides in 2009, around 36k, with a huge portion done using guns(not sure that is in there, I just know that from somewhere).
Murder rates in the states are, meh, as in they are bad and gun crime is bad, and getting rid of guns would reduce some gun crime. At this point a ban on guns will remove mostly guns from mostly legal places there were in incredibly little danger of being used for crimes.
Think of it like this, 2009, 16k murders, lets guess 2/3rds were also by gun, call it 11k, how many would the 30 or so murders at this school have contributed from a legally owned gun?
Male to female homicide ratios were 3.4:1, black murders vs white murdered 5.4:1. So of the 16k murders 13.5k were black people and of those the vast majority were men. Is every black man murdered in a gang, absolutely not, the severe disparity in the numbers though, is very obviously effected by gang culture. Stats without gang related crimes would be VASTLY different.
But the main problems are, people who go on killing rampages go on rampages for many reasons, because guns are available isn't one of them. Getting rid of legally held guns, would do very very little to remove guns illegally held, by gangs, who are responsible for the VAST portion of murders and gun crimes in the states.
Would if effect the stats, sure, would it effect them significantly, no. Did this crime have anything to do with guns themselves, or everything to do with a mentality unstable person going bat **** crazy.
Gang culture and gun crime NEEDS addressing, but it always did, and it has nothing to do with crazy people going on rampages. This is the problem, politicians are being given an easy way out, ban the M4 copy the kid used, everyones happy, nothing is done about ghetto's, nothing is done about gangs, the murder rate/gun crimes won't change much at all... psycho's will still go on rampages, using other guns, or other weapons entirely and nothing will change.
people need to focus on two separate issues, and not let politics package this up in a "we've identified some stupid reason this happened, will fix this little thing and pretend everythings better" bow and not go after the fundamental issues underneath.
For murder rates/gun crime change in america, you need to battle extreme poverty, attitudes, culture, ghetto's, education and jobs. To battle psycho's going on rampages you need, better parenting, better nets to catch these people, better education, better treatment.
This kid I would be SHOCKED if he didn't display lots of outward signs of well, being a psycho, parents probably should have done something, doctors, teachers. Someone most likely missed something that shouldn't have been missed, a anti-gun law won't change whatever screwed this kid up in his life.
