To conceal their illegal activities (RICO ACT). When I attempted to utilize the "chain of command" within my Federal Employment, I was "targeted" for acts of RETALIATION including the loss of thousands of dollars in wages and INTERROGATION/INTIMIDATION by corrupt Postal Inspectors, who then LIED to their superiors as to their own actions in regards to their treatment of me. I personally have lost thousands, but my fellow "craft" members have been DEFRAUDED out of MILLIONS so far! The employer has even gone so far as to pay out millions to conceal the indiscretions of their managerial personnel, rather than face the financial liability of "treble damages" under the RICO ACT that would be in the neighborhood of 50 MILLION DOLLARS!
