On the right, that is not a crewcut. By male standards, it is a thick, sweeping mane of hair.
They are NOT the same guy, and there is no basis to think they are even related.
They look about as diverse as two men can be. They not only do not look identical; they don't look remotely alike. They have no similarities at all except that they are both white males. The differences between them are stark and polarized.
So, why is anyone claiming that they are the same man?
It's because the "JFK community" is also polarized and not by the division of LN and CT, but rather by the division of LN+CT vs. real Oswald defenders. Real Oswald defenders will admit that that guy on the right is NOT Lovelady. He couldn't be Lovelady. He was a phony Lovelady impostor from a phony clip designed to tell a phony story of Lovelady wearing a plaid shirt. It is a fake, a lie, and a fraud, and it is an outrage that all will not admit it.
