My take on JFK Conspiracy Theories and Theorists.

[DanTex]

138. From what I've read, the impersonation theory has been pretty soundly disproved.

There is a CIA photo of someone who is not Oswald outside the Russian Embassy around the same time, which some people mistakenly matched up to the name Oswald, but the people working at both Cuban and Russian Embassies testified that it was the actual Oswald that was in there. There was also an initial statement that Hoover had reported evidence of a phone conversation by a fake Oswald, but that turned out to be the result of an error. The article you link to doesn't appear to demonstrate anywhere that a fake Oswald was actually recorded on the phone, only that some evidence is missing.

Proof that someone was impersonating Oswald would be noteworthy. Proof that some tapes are not accounted for or that the CIA/FBI withheld evidence is not. We already know that the CIA and FBI were less than forthcoming to the Warren Commission, but that doesn't prove that they were involved in a conspiracy, it just proves that they are secretive organizations that were trying to cover their asses.

Still, like I said in the OP, in light of the forensic evidence, this kind if conspiracy is the only kind that is possible: a conspiracy in which Oswald and Oswald alone shot JFK, but maybe some other group helped him. But, there's still no evidence for it.
