Video Shows Tsarnaevs Working Out Before Bombing

CNN has video that manages to come off as mundane and chilling at the same time—the Tsarnaev brothers getting in shape at a local gym three days before the Boston Marathon bombing. One thing of note: The gym manager says he was surprised to see Tamerlan show up with his bushy beard shaved off, without explanation. Tamerlan also refused to remove his shoes (Dzhokhar complied quickly), and the manager said he later sent an email to his boss asking to have Tamerlan banned because he was an arrogant jerk.
