Previously, the N.S.A. filtered information before sharing intercepted communications with another agency, like the C.I.A. or the intelligence branches of the F.B.I. and the Drug Enforcement Administration. The N.S.A.’s analysts passed on only information they deemed pertinent, screening out the identities of innocent people and irrelevant personal information.
Now, other intelligence agencies will be able to search directly through raw repositories of communications intercepted by the N.S.A. and then apply such rules for “minimizing” privacy intrusions.
