Benjamin Witte makes a GOOD POINT:
It is very important that the remaining suspect be taken alive.
The New York Times has identified the two suspects as Chechen brothers, Dzhokhar A. Tsarnaev [above], 19, and Tamerlan Tsarnaev, 26—the latter of whom is apparently dead. The most important thing, of course, is to apprehend and stop the remaining suspect before anyone else is killed or hurt. That may require the use of lethal force, and the state and federal law enforcement officers who are dealing with this situation will use their best judgment as to how to protect the public—and themselves.
