Just caught up with the thread.
In some dark place, Ted Kennedy must harbor deep resentment that the CIA, FBI and US military intelligence could not save his brothers from the murderous hatred of Oswald and that Muslim, Sirhan.
His violent anti-war appeasement approach - the same evil that influenced his brothers' murderers.
Considering old Joe Kennedy was totally lacking in honor and/or integrity it is not surprising that the children are as untrustworthy.
