I’m covering the breaking news on the search for Dzhokhar Tsarnaev in the main thread, but this is a good backgrounder for what comes next, as well as what came before.  Former FBI agent Don Borelli says this reminds him of the Mumbai attack, watching the suspects “move with a purpose.”  Borelli warned that we can’t come to conclusions, but we will be “relying on our foreign intelligence partners.”

I’d say that the same calm and purpose shows training specific to the task, as well as the shootout, but they could just have trained each other.  We’ll see soon enough.
