Foster was not "offed" at Ft Marcy park. He was dumped there. When he was found at the park there were no car keys on him. After someone in the Clinton admin went to see the body at the morgue, his keys were mysteriously found in his pocket. They planted the gun in his right hand but Foster was left handed. That's just a couple of the anomalies in the Foster "suicide" case.
I'm convinced he was murdered at the white house, probably in his own office and maybe even by Hillary herself.
But that would mean that someone would have to sneak a gun into the white house. It would mean that someone would have to discharge it without alerting the secret service. And get the body out the back into a car without anyone noticing. Perhaps, but?
