Boston bombing suspect Tamerlan Tsarnaev interviewed by FBI in 2011 named listed on TIDE
Boston Bombing Suspect Tamerlan Tsarnaev’s Name Listed Classified Government Watch List TIDE

The name of deceased Boston Marathon bombing suspect Tamerlan Tsarnaev was listed on the U.S. government’s classified central database of people it views as potential terrorists, Reuters reports. Um, this begs the question of why they weren’t keeping better tabs on him. His name was listed on the “Terrorist Identities Datamart Environment” list, known as TIDE.

The sources said Tamerlan Tsarnaev’s details were entered into TIDE, a database maintained by the National Counterterrorism Center, because the FBI spoke to him in 2011 while investigating a Russian tip-off that he had become a follower of radical Islamists.


But the database, which holds more than half a million names, is only a repository of information on people who U.S. authorities see as known, suspected or potential terrorists from around the world.

Because of its huge size, U.S. investigators do not routinely monitor everyone registered there, said U.S. officials familiar with the database.

As of 2008, TIDE contained more than 540,000 names, although they represented about 450,000 actual people, because some of the entries are aliases or different name spellings for the same person. Fewer than 5 percent of the TIDE entries were U.S. citizens or legal residents, according to a description of the database on the NCTC website.

Separately, Tamerlan Tsarnaev, his wife Katherine Russell and their three-year old daughter got Massachusetts welfare benefits in 2012.  He and his brother, Dzhokhar Tsarnaev received welfare benefits through their parents when they were much younger. They took from us and then they bombed innocent people.
