Fetzer gets a listing in Urban Dictionary: 'Fetzering' is a term for talking balls.

[Albert Doyle]

For what it's worth most sensible people see that Fetzer's Cinque-based evidence of Oswald being in the doorway is based on bizarre imaginary forgeries and photo alterations. It could be that Fetzer has been overstressed by his efforts at exposing conspiracy evidence in combination with very poor photo analytical skills. It's sad Fetzer doesn't realize his offerings are little different than a Monty Python skit, except he's serious. The only thing I can defend him on is I agree that the limousine stop is valuable towards showing the Zapruder Film is altered and that alteration of the Zapruder Film seriously qualifies the evidence for conspiracy. However I would be extremely interested if this was some kind of high-tech mind control done to Dr Fetzer.
