FBI Records - An Historic Declassification
From the FBI:
Imagine a library filled with a million books, each 270 pages long.That’s how many historic FBI pages we declassified on December 31, in line with an executive order that now applies to the Bureau. . .
. . . That won’t happen overnight. “Just because the files are officially declassified doesn’t mean they are automatically ready for public review. We have a lot of work to do before that happens,” explains Hardy.
Such as: Scouring for—and then redacting—information that would compromise personal privacy or would expose a government informant, identify a sensitive technique, or violate a treaty or agreement with another country.
