You may be interested to know that "Tommy the Cork's" old law firm (bearing his name) is alive and well and a son is still quite active in that shop. I do not know about their ongoing lobbying business but they are quite close to the NSC and the unitary/imperial presidency crowd.
In your list of players in the network, some are vastly more important than others. You have serious policy makers (even Bilderberg participants) alongside "mechanics."
I would have confidence in Morganthau's opinion about TC.
You should know that McCloy (CMB) was at Murchison's house on the evening of 11 /'21/63 along with J.Edgar Hoover, Nixon, H.L. Hunt, Cabel, George Brown, others in the 8F group, and eventually LBJ., whose mistress became a dear friend of mine, and who was also there. She also, along with other Ruby girls saw Oswald and Ruby together on various occasions. The deed was confirmed between 10 and 10:30 PM in M's study.
A closer more personal account is contained in Barr McClellan's book in which he also claims to have made a fingerprint match from the Book Depository nest of a shooter other than Oswald, who was contracted by LBJ's Clark law firm.
Anyway keep on the historical framework and context. It is important.
