A video on YouTube contains one of the rare interviews with L. Ron Hubbard. Unfortunately, it has been very heavily edited and distorted.
For example, zoom to 2:55 where Hubbard is asked to answer the question "what is Scientology". He starts to explain the origin of the word, then the commentator at 3:38 ask him to be more concrete. He let Hubbard state one single sentence then cuts abruptly and on 3:47 jumps to another out of context sentence that for the layman would be difficult to understand. Then the commentator claims "even after three hours of talking, we never got an explanation from him that we could understand" and goes on to provide his own (irrelevant and biased) interpretation. They didn't even allow the viewer to decide this for himself by letting Hubbard speak more than two sentences, mounted in such a way to make it look absurd!
This gives the tone of the whole footage. Out of three hours the team made a 26 minutes footage containing very little of the actual interview and loads of their own derogatory comments. They just selected out the few minutes in the interview that fit their obviously biased point of view.
The full uncut version of that interview is unfortunately not available.
