So are the facts.
In 2011, the American FBI questioned one of the suspected brothers in the Boston attack - Tamerlan Tsarnaev - and his relatives on request of the Russian FSB. This was reported by the BBC News citing sources in the US government and intelligence services.
The Russian FSB suspected that Tsarnaev joined the "radical Islamists" and intended to go to Russia, said a source in the US government.
Two years ago, the FBI interrogated Tsarnaev, his relatives and friends in connection with an appeal of Russian security services, but found no evidence of his involvement in "terrorist activity in the US or abroad".
The US authorities also reported that the murdered Tamerlan Tsarnaev spent six months in Dagestan in 2012. There, as supposed by The New York Times, he could get under the influence of the "terrorist underground".
His father, Anzor Tsarnaev, claims his son returned to Russia to get a new passport, but for some reason, his stay was delayed, the newspaper said.
And now the questions of the FBI to the FSB:
- Why didn't the Russian FSB detain or question, or at least conduct a "prophylactic conversation" with Tamerlan Tsarnaev when he was on the territory of Russia and Dagestan? After all, the FSB specifically asked Americans to report on Tsarnaev, fearing that he might come to Russia with "terrorist intentions". And this despite the fact that KGB literally arrest at the airport even ordinary Chechen refugees, who for various reasons, are deported from Europe.
And here an "element of interest of the FSB" delivered himself into the hands of this agency.
- Did the FSB spy on the movements and contacts of Tamerlan Tsarnaev? If it did, and he "fell under the influence of radical Islamists", why didn't it arrest him, or at least warn the American FBI?
And if the FSB did not keep track of the contacts and movements of Tamerlan Tsarnaev, why didn't they do it, since the inquiry of the FSB to Americans said that he was going to come to Russia to join "radical Islamists"?
The American FBI would also ask the Russian FSB the following question:
- Did the FSB agents get into the contact with Tamerlan Tsarnaev ostensibly on behalf of the Caucasus Emirate? If contacted, then for what purpose? Did the FSB want to find out his intentions, or was the FSB aim to beguile Tsarnaev to advantage on the American soil?
And finally one more question:
- Who benefits from this?
- Who benefits from this whole situation even if the bombings were really carried out by the Tsarnaev brothers?
The AP, referring to experts, pointed out that "Caucasian connection" in Boston bombings could persuade the United States to work more closely with Russia in the fight against the "terrorist threat" for the olympics in Sochi.
"The US intelligence agencies would be more interested now in expanding cooperation, which has hardly existed until now", the AP quoted Andrei Soldatov, a Russian journalist and security expert.
"The most important lesson for the United States in this story would be to enhance cooperation with Russia in the fight against terrorism and filling it (partnership) with real content. Given the roots of the current terrorist attack in Boston, the US should be interested in sharing information with the intelligence agencies of the Russian Federation on terrorist groups operating in the North Caucasus and having a network structure in other countries", said the editor-in-chief of a Russian KGB journal "National Defense" Igor Korotchenko to the Russian KGB RIA News.
"The US has an excellent technology for satellite reconnaissance and electronic interception, in addition, both the CIA and the FBI have some operational and analytical information on international terrorist groups", the Russian KGB thug Korochenko said.
