I don't consume broadcast media other than the odd snatch of NPR in the car, or watching online videos of segments which for some reason have been recommended to me or caught my eye. My understanding of the bombings thus far has been from a mix of (mostly) liberal blogs and the some news Web sites, as well as secondary commentary from those sources.
While I have my own private views of what is likely to be uncovered about the perpetrators, I am the first to acknowledge those views are currently not grounded in any facts whatsoever. Therefore I decline to speculate in public pending reliable evidence emerging.
What I will say is this: I hope for swift justice tempered by mercy. I likewise fervently hope that we can avoid another national paroxysm of retributive anger like that engendered by 9-11. Despite our manifold imperfections, we are a nation of laws, and a people who value a moral and orderly world. Our internal disagreements are for the most part about what those ambitions mean.
Please, let America be lawful and orderly in our response to this terrible event.
