from Esquire's Charlie Pierce who says what I've been thinking and says it 100 times better:
The sawhorses were comforting because the events of the past week are now getting fed into a number of gigantic maws, none of which are likely to do the rest of us any good. They are being fed into the big media maw, with speculation now completely rampant as to what launched the Tsarnaev brothers on their crime spree. While Dzhokhar Tsarnaev was still at large, with a few notable exceptions -- coughNewYorkPostcough -- big media went out of their way to appear responsible. Now, though, with the younger suspect on a respirator at Beth Israel, all the shackles were off, and we spent the day hearing wild speculation of what may have been behind the murderous doings in and around Boston last week. The events also are being fed into the maw of big politics with the federal government invoking the "public safety" exception to the Miranda ruling in connection with a 19-year old who is, at this moment, breathing through a tube and who, anyway, by all the evidence available at this moment, appears to be still little more than Dylan Klebold with a funny name and a pulse.
