Those who would trade freedom for safety niether deserve nor will get either.
Guns are made to kill. And not just people. We have in the country a severare problem with overpopulation of animoles. Guns are the only usefull way to control that. If you don't control the problem you will soon starve to death all (Not just the excess) of our wildlife. We need guns because the DNR cannot mantain wildlife iwthout them. And don't say we need more preditors, it sounds good until there is a bear eating your garbage, or a wolf snapping at your heals. Both are currently afraid of people in general, but campgrounds in some areas are in danger because bears have come to see people as in the way of food, and then they kill to get at the food you carry. Wolves will be next.
I have never heard of a gun sitting on a shelf killing someone. I have heard of people mishandling a gun and killing someone (this is rare, but it happens), I've heard of people intentially killing anouther with a gun. There are also many people who handle a gun safely. Hunting is the safest sport we have today despite the fact that there is almost always someone in range of a hunters gun, and there is no supervision of hunters. The reason is that hunters know and respect the deadlyness of their weapon, and (generally) kill only what they intend to kill.
Guns are not the common link in kids killing other kids. They are a common link in kids shooting kids, but that is not logical as you have defined guns when shooting, and of course they are a common link then. Bombs have destroied schools in the past, bombs made from standard household chemicals. Quit defining your goal and then restricting your scope to where your goal is achived and your logic will improve.
I have yet to see a convincing arguement that people are not the common link in all these school shootings/bombings, or other killings outside of school.
And finially, isolated incidents do not a crisis make. Yes of course I would be sad and angry if someone shot my sister. But I would not use that as an excuse to apply mislogic. Guns are not a big problem in our socity, they look like an easy fix, but it is not.
