(AP Photo/Bob Leonard) (Newser) – If you found yourself wondering why in the world the Tsarnaev brothers would allegedly admit their role in the Boston bombings to a guy they carjacked, then stop for snacks (giving said guy a chance to escape), well, you aren't the only one. On Mother Jones, Tim Murphy lists those two moves in his list of 11 befuddling things the suspected bombers did: Dzhokhar failed to disguise himself: In surveillance photos, he's wearing a backwards hat and no sunglasses, which made him easy to ID. He also failed to react to the first explosion: Surveillance video shows that he only looked over briefly when it happened, according to the complaint filed in federal court yesterday. That was a big tip-off to investigators. They didn't flee the city: Rather, they stuck around for days, during which no one knew of their involvement, doing things like leaving their car in the auto-body shop, going to the gym, and partying. They killed MIT police officer Sean Collier: Why? We don't know yet, but that's what ultimately caused the manhunt, Tamerlan's death, and Dzhokhar's capture. They kept their hostage's phone: The police tracked them through the phone's GPS. Click for Murphy's full list.
