The Boston Globe is among many media outlets to report this weekend that Russia was surveilling suspected bomber Tamerlan Tsarnaev in 2011, and “warned the FBI of the alleged bomber’s radical shift” towards “suspicious activities.” The FBI acknowledged Friday that it has investigated him in 2011, after that prompt, but “did not find any terrorism activity” in the behavior they observed online and in person, when they interrogated him at his home. The 26 year old was killed early Friday morning during a firefight with police in Watertown, MA. Bonus: The name of the boat his brother Dzhokhar was found hiding in, on Friday? “The Slipaway II.”
