Thirteen years, three different presidents, three similar tragedies

Talking Points Memo's David Kurtz put together a "mashup of Clinton, Bush and Obama reacting to the news of Littleton [AKA Columbine], Blacksburg, and Newtown." The effect is striking. Is that old saw about those who don't know the past being doomed to repeat it ever true or what? It's like a skipping record, playing the same rotten song over and over and over. 13 years since Columbine and we've made no progress whatsoever.

We can't let this just fade into history like every other mass killing. We have to do something this time. And if that means changing Americans' attitudes toward guns and shifting public opinion back to sanity, then so be it. If it's a long slog, it's also a necessary one.
