I guess Charles Pierce now qualifies as a "wacko CTer".

67. That Oswald and Oswald alone shot JFK is certain well beyond reasonable doubt.

You are right, that still leaves room for a conspiracy, because Oswald could have been working for someone. There's no evidence of that, but it is still much more plausible than any theory that denies that Oswald fired the fatal shots or insists on a second gunman. But article cited in OP doesn't bother and make that distinction, and in fact specifically says "I don't know if we'll ever settle who shot from where". This is wrong. We know who shot and from where.

The problem with articles like the one in the OP is that they abandon even the pretense of reason, and throw all the evidence into the same "we may never know" bucket. It almost seems like a deliberate attempt to place the JFK assassination in some mythical place immune from logical deduction. Actual evidence -- things like fingerprints, and witnesses, ballistics, medical evidence, and so on -- are all tagged as being part of "the official story someone is trying to sell us", so they can all be simply dismissed offhand.
