I once asked for some IV&V information on US-DAV's claims...and got a snotty answer for my trouble. Mr. HC's answer looked to be about the same as the one AV gave me.
As I see above that someone has Pinged American Victory, he deserves a fair chance to confirm or deny this speculation or to offer insight if he knows Cafasso. That is pertinent as Cafasso said in the Doric letter I found: "I am a retired US Army Lt. Colonel and a Policy Advisor to an Organization named US Defense-The American Victory, chaired by Admiral Mark Hill,USN/Ret.", which seems to be the same name of the group AV was saying he was a member of on the post in question.
Of course, if AV doesn't wish to go through the task of doing enough convincing and discussion with others so that they won't bring it up when they encounter him on the board, he could just issue an opus and close his account. It would be wonderful reading.
But remember, he has been here three and a half years and deserves fair treatment if he wants such.
