McCloy of the WC made the same observation as you...although McCloy, in a conversation with Blakely, seemed to hint he thought there was more to the LHO story than known. "We just couldn't find evidence of it." said McCloy, or something to that effect.
Of course, other members of the WC ended up expressing reservations about the WC finding, including Richard Russell (for reasons related to my reasons), Hale Boggs and Cooper.
I still wonder why State Dep't careers were ended for even asking about LHO-G2 links.
I have belabored my views herein why I think there were likely three physical participants in the JFKA, so I will let it rest.
I have shown my case for a JFKAC to my satisfaction, but since I cannot even begin to show who were LHO's confederates, I won't pretend to know who they were.
The leftists and rightists, and anti-Semitic crackpots who fabricate elaborate JFKA CT's...well, they have never come even close to making a case.
But keep in mid---a very small, ad hoc informal plot, involving only the immediate participants, would be impossible to detect without actual capture of those participants. Only one was captured, and he soon dead.
