What is wrong with the world?

Four school shootings in the United States in one week. What is going on in our world? It scares me, because the one in Chicago today happened in a lecture hall, and if you think about it, how on earth can a university prevent it? I mean, I was sitting in Political Science today and if someone came in with a gun I would have no where to hide, no where to go. I really hope that nothing like that would ever happen at Carleton, and the fact that I live in Canada makes me feel safer, but still. It scares me, because there is no way to prevent these things from happening, guns are not the most difficult things to conceal, and even if you didn't want to you could walk right in with a gun. Campus security has been an issue at Carleton, but a sexual assault, while horrible, is minor in comparison to someone opening fire in a lecture hall. Four shootings, four parts of the United States, is anyone really safe? My heart goes out to all those that have become victim, all those that knew someone, and everyone's families. My belief in the good of humanity is further diminished, and I hope that maybe the next President of the United States will finally do something about gun control, in hopes that in the future these events will not occur.
