The USA Merit Systems Protection Board published an online Opinion and Order which involved a TSA employee. A footnote states:
*The original unexpurgated version of this Opinion and Order contains Sensitive Security Information (SSI) protected by 49 C.F.R. Parts 15 and 1520. Per agreement between the Merit Systems Protection Board and the Transportation Security Administration (TSA), the TSA has redacted all SSI protected by 49 C.F.R. Parts 15 and 1520 from this version so that it can be made available to the public.
The SSI redactions were made in an insecure manner and could be easily removed.
As it has done in similar situations, Cryptome provides the unredacted version.
