In case you were wondering what the Russians told the FBI, here you go:

Deceased Boston Marathon bombing suspect Tamerlan Tsarnaev was identified by a foreign government as a “follower of radical Islam and a strong believer” whose personality had changed drastically in just a year, according to the FBI. As investigators considered possible motives for Monday’s fatal bombings, U.S. authorities acknowledged that an unnamed government had contacted the FBI to say the 26-year-old ethnic Chechen “had changed drastically” since 2010 and was preparing to leave the United States “to join unspecified underground groups,” according to an official statement from the FBI.

This report specifies “a foreign government.” That’s obviously Russia — duh! — but if you require confirmation, here it is.

When the two ethnic Chechen suspects were identified, the FBI said it reviewed its records and found that in early 2011, a foreign government — which law enforcement officials confirmed was Russia — had asked for information about Tamerlan Tsarnaev. The FBI said it was told that Tsarnaev was a “follower of radical Islam” and was preparing to travel to this foreign country to join unspecified underground groups.

WHAT DIFFERENCE, AT THIS POINT, DOES IT MAKE??? THERE ARE FOUR PEOPLE DEAD!!!
