No group came forward to claim the credit for the Boston Marathon Bombing. Russia did however rally round the Tsarnaev family and the Todashev family. Could Tamerlan and Dzhokhar Tsarnaev have been working for Russia? To get favor for their family still in Russia?
If the Tsarnaev brothers did it alone with no help, why doesn’t Dzhokhar tell us which brother shot the MIT police officer Collier? (Assuming they did.) Why not telling us more about making the bombs, test runs, etc.?
Dzhokhar was very concerned in his court statement to push the Moslem button. Is that to hide the Russia connection? Distraction operation to the end?
By protecting Russia, Dzhokhar would be protecting his family in Russia. This is all he has left to do on this earth.
