WhoWhatWhy has discovered that the FBI secretly flagged at least one of the “Boston Marathon bombers” as a terrorist threat in his immigration records, despite publicly denying it had done so.
This designation existed right up to the time the bombs went off at Boylston St. on April 15, 2013.
Tamerlan Tsarnaev’s heavily redacted immigration records, known as an A-file (alien file), were released in February under the Freedom of Information Act and posted online by US Citizenship and Immigration Services (USCIS). FOIA has a “frequently requested record” provision where multiple request for the same record triggers a “reading room” (posted online) treatment of the records. WhoWhatWhy was one of those requesters.
