Great job pasting that Youtube link Bill! That's some impressive research.
As for the actual video. That's 6 minutes of life that nobody will ever get back. Here we see a guy named Steve Shives use the usual LN tactic of argument by appeal to ridicule, without ever actually addressing any reasons for believing the narrative.
His "5 Stupid things":
1. The endless list of potential suspectsThis is the usual strawman that says that every CT believes every conjecture that has ever been brought forth. As an amusing aside he talks here about preferring the "explanation that requires the fewest assumptions" as if the WC explanation isn't absolutely loaded with assumptions.
2. The equally endless list of possible motivesAs opposed to the WC's lack of
any motive.
3. The lack of a coherent counter-narrativeAs opposed to the WC's lack of a coherent narrative to begin with.
4. They attract people who aren't normally conspiracy theoristsI'm not sure why he considers this "stupid". But this may have something to do with this case being nothing like conspiracy theories like the moon landing hoax or Bigfoot, despite some LNers' best attempts to paint them with the same brush to avoid actually talking about the evidence.
5. They combine to form the perfect storm of conspiracy theoriesAlso not about anything stupid. I think Steve lost his train of thought halfway though the video. Here he shows a cute graphic with JFK's picture and the quote "Ask not what the evidence says happened. Ask what sounds good to you". Which in fact describes perfectly how the WC came to their conclusion.
Nice try, but a giant fail on multiple levels.
