I'll give you my take on Buell Frazier.
Buell Frazier is an instrument of the Establishment, and he is no friend of Lee Harvey Oswald. He is a traitor to Lee Harvey Oswald.
I know he says that Oswald was a nice guy, and that he liked children and took the time to play with them. I bet he thinks Oswald liked puppies and kittens too.
And, I know he often says that Oswald's paper bag was only 24 inches long, and therefore, not long enough to contain the rifle. But, truth be told: that doesn't mean a damn thing. It doesn't help Oswald in the least. Why? Because it's nothing new. It's what he has said all along, starting in 1963. It's part of the lore of the story. It's part of the JFK status quo. And the other side just says that he is mistaken about it and that it's easy to be mistaken about it. And so, there is a stalemate, and that particular stalemate will likely be in the same place 100 years from now as it is today- other factors being equal. So, he is not doing Oswald any good by saying it.
But, the other side doesn't mind that he says it. They still treat him like a celebrity. Doesn't he get invited to the Sixth Floor Museum to do interviews and give talks? You can't get more "establishment" than that when it comes to JFK.
It actually helps them that he defends Oswald some. That's because they know it enables him to win favor with Oswald defenders. And then, when he tells them that Doorman was Lovelady, they are inclined to believe him.
They can live with the paper bag conundrum. They've been living with it for 53 years. What they can't live with is Oswald in the doorway. That can tear down the whole edifice.
Is there any hope that Frazier will do the right thing? The only hope is that Frazier, like E. Howard Hunt, will make a death bed confession and admit that it was Oswald in the doorway. But, I don't think there is any chance that he will do it before then because it would be too traumatic for him, and he couldn't handle it. But maybe, just maybe, he'll come to his senses and realize that he needs to do the right thing before he dies, before it's too late, and admit that it was Oswald in the doorway. Let's hope he has a conscience.
