The EFF is a non-profit with a stated goal to protect online privacy. The FBI hopes to add more sources of information to their database, including airline manifests from the Department of Homeland Security, the Postal Service’s change of address database, the national Social Security number database, and 24 other unidentified databases whose names were redacted in the released report.  Whether or not sacrificing personal information privacy is worth it to catch terrorists is up to the reader to decide.
