Gun Control, Please!

So apparently there's been another one of these random mass shootings, this one in Colorado. I have nothing to say on the subject, except that a) it's obviously a horrible tragedy, and b) can we please, please, please stop pretending that the abject failure to have any kind of meaningful gun control didn't contribute to these people's deaths? And the deaths of scores of other people who've been killed in previous such shootings? And, having so admitted, can we please decide that the whole insane gun rights thing just isn't worth all the dying? Please?
