Slate‘s Emily Bazelon explains why you should care that Dzhokhar Tsamaev has not yet been read his Miranda rights:

There is one specific circumstance in which it makes sense to hold off on Miranda. It’s exactly what the name of the exception suggests. The police can interrogate a suspect without offering him the benefit of Miranda if he could have information that’s of urgent concern for public safety. That may or may not be the case with Tsarnaev. The problem is that Attorney General Eric Holder has stretched the law beyond that scenario. And that should trouble anyone who worries about the police railroading suspects, which can end in false confessions. No matter how unsympathetic accused terrorists are, the precedents the government sets for them matter outside the easy context of questioning them. When the law gets bent out of shape for Dzhokhar Tsarnaev, it’s easier to bend out of shape for the rest of us.

An American being charged for a crime committed on our soil.  Should be simple, right?
