Yeah, it may LOOK like the same guy, but that doesn't mean it is. Besides, the thug had sideburns and his head looks it tapers. Trying to match two people from poor pictures, is NOT proof of anything.... just a wild stretch. There are other details, but quite honestly, unless you have some more proof than that, there's no point even considering such a connection. By your measure of evidentiary validity, I might also conclude Kerry was the guy who played Lurch on the Addams Family.
