Dzhokhar Tsarnaev Unarmed During Backyard Boat 'Shootout'

That didn't stop the cops from shooting

The FBI's not saying what led police to fire on the boat where Boston bombing suspect Dzhokhar Tsarnaev was hiding, as they reveal he was unarmed while hiding in the boat during a stand-off that lasted an hour and a half. His older brother, who officials say said he wanted to die for Islam, died after a firefight with police. Officials say he may have been run over by his own brother, Dzhokhar, who they say fingered him as the mastermind of the bombing. During the initial chase, cops also fired on a state police vehicle they thought the suspect was driving
