My bias: I happpen to believe that private citizens should be allowed to own firearms.
I see no reason why governments (and criminals) should have the monopoly and historically some of the biggest "gun control" advocates were also some of the worst tyrants. (Hitler even went so far as to prohibit Jews from owning knives and clubs.)
That being said, when you study the details of school shootings, the facts are always more than a little screwy and rarely hold up under any kind of serious analysis.
Take the recent school shooting reportedly by Seung-Hui Cho at Virginia Tech.
My first question is WHO was this guy?
It's actually not that easy to kill as many people as Cho did with the weapons he used.
If in fact Cho was the shooter (or the only shoooter), he had a proficiency with firearms that was nothing short of supernatural.
Skills like the kind exhibited are the result of serious, high level training.
Where did Cho train? Who trained him? On these points, the ever-babbling news media appears completely mute.
