George Hill, a retired supervisory intelligence analyst who worked out of the FBI’s Boston field office, recounted that the bureau’s Washington field office (WFO) pressured officials in Boston to open investigations on 138 people who attended a rally on Jan. 6, 2021, even though there were no indications the people violated the law.Hill said Boston officials questioned why they couldn’t get access to the tranche of some 11,000 hours of footage from inside the Capitol.
"Because there may be—may be—UCs, undercover officers, or ... confidential human sources, on those videos whose identity we need to protect," Washington-based officials responded.
