Picture which prosecutors say shows Boston bomber is ‘unrepentant’

Boston Marathon bomber Dzhokhar Tsarnaev peered into the security camera in the corner of his jail cell, fussed with his hair while looking in the reflective glass, flashed a two-digit salute like a teenager taking a selfie and then defiantly put up his middle finger.

A photo and video footage of the obscene gesture were released publicly Wednesday, a day after the photo caused a sensation when prosecutors showed it in court to the jury that will decide whether Tsarnaev lives or dies.

The images were taken by a video camera in Tsarnaev’s cell three months after the April 2013 marathon bombings killed three people and injured more than 260. It was the day he was taken into court to be formally arraigned on 30 federal charges in the bombing and in the killing of a Massachusetts Institute of Technology police officer.

Prosecutors presented the photo, wedged between vibrant photos of the people Tsarnaev has been convicted of killing, during their opening statement, telling the jury it showed an “unconcerned, unrepentant and unchanged” Tsarnaev.

On Wednesday, Tsarnaev’s lawyers tried to blunt the impact of the photo by showing video of Tsarnaev in his cell before and after.
