I think this thread is quite revealing and actually confirms everything I've always said. That is, people who think the government got it right on Kennedy's murder actually, deep down, don't like Kennedy, the family or whatever. So there's a heavy dose of bias involved.
It reminds me of the investigator who hated women in general, and whores specifically. Suppose a whore is found dead in an alley and this investigator has to find out who killed her. He'll do the least amount of work and secretly write it off as, "Eh, she deserved it."
The same here with Richard and many others who think the Feds got it right. They really don't like Kennedy and, therefore, Oswald did it alone and deep down, Kennedy "deserved it." I sure wouldn't want those kind of people investigating my loved one's murder.
