Speaking at a memorial service for slain M.I.T. officer Sean Collier, vice president Joe Biden called the Boston marathon bombers Tamerlan and Dzokhar Tsarnaev “two twisted, perverted, cowardly, knock-off jihadis here in Boston.”
The Tsarnaev brothers shot Collier last Friday as he was sitting in his squad car and proceeded to engage in a firefight with police officers that resulted in the death of Tamerlan Tsarnaev.
