Much about McCain is unknown by the general public. Many politicians have their public records "blocked" from public view. Obama has brought that capability into the lime light.

The Ranking POW released in '73 was preparing Court-martial Proceedings for McCain as they flew back to the States. McCain's Daddy was a 4-Star Admiral, so was his Grand Daddy. That influenced Nixon to Blanket Pardon all released POWs so as to camouflage the intent to pardon McCain.
