People go to great lengths to fabricate military service. For every real Navy SEAL the FBI estimates there are hundreds of impostors. Xavier Alvarez, for example is an impostor. Alvarez, once a member of a California water-district board, lied at a public meeting about being a war hero specifically that he was awarded the Medal of Honor. But his lies did more than make him an outcast. They made him a criminal. Jeffrey Rosen, is professor of law at George Washington University.
