And that marks another one of the mystifying things that these two did before, during and after the bombing.

the carjack victim has told police that Tamerlan Tsarnaev and his brother pointed guns at him and, in an apparent effort to intimidate the victim and dissaude him from trying anything foolish, Tamerlan Tsarnaev told him, “We just killed a cop. We blew up the marathon. And now we’re going to New York. Don’t [expletive] with us.”

Why telegraph their intentions to the carjack victim, let alone let the guy live? If that was what they were going to do - why give cops a chance to catch up to them and get a better description on their whereabouts.

Don’t get me wrong, I’m thankful that this duo engaged in as many boneheaded and head-scratching acts as they did; it’s those actions that helped catch them and may have prevented further bloodshed - in NYC or en route.
