JollySovereign: You want to know what the real problem is with these shootings? The fucking media that has it on 24/7 and spins the story so much it becomes nothing but pure sensationalism and appealing to emotions. Even if the shooter played violent shooting video games you're not looking at the problem as a whole. People like Fox News and 'social scientists' like Jo Frost (who blamed most of the London riots in 2011 on video games) just use ALL video games as a scapegoat for the mental problems of these shooters because of social stigmas they still cling to thats been outdated for about 20-30 years now.
The real problem is how the media covers and sensationalizes these killings. I think this video, specifically the forensic scientist at the end, pretty much sums up the problem with news coverage of the killings and the link it has to a lot of recent mass shootings in America.

There are millions of responsible, law abiding firearm owners that would never in a million years do something like this. It is much, much, much easier to say that firearms need to be outlawed rather than getting to the root of what causes these things to happen.
Outlaw guns, but not address the societal problems and mental issues that some people have? You've still got the potential there for massive casualties, given the ease with which people can find ways of doing mass harm, especially with the internet. It is always easier to treat the symptoms rather than finding the cause of such problems.
What is it that is causing these young males (because it is, most of the time, young males) to go off like this? Is it stress? Lack of education? Lack of opportunities? Loss of feeling any sort of control over their lives? Abuse? There's a whole shitload of avenues that could lead to these events, but they would all take real effort to combat, rather than being able to pat yourself (generic "yourself" here) on the back that you got firearms outlawed on the back of a parent's grief and loss.
In a way, it is similar to the anti-abortion debate. People want to outlaw the symptom (abortion) but not address the underlying issues. By thinking that they outlaw the most obvious expression of it, the problem itself goes away.
