It is of a Clearwater, FL City Council Meeting in the early 1980s. The description posted on Google Video is:
Brown McKee had spent 24 years in Scientology by the time of these hearings.
He was a Scientology "mission" holder in Connecticut and was present at the infamous 1982 meeting in which mission holders were strong-armed into accepting new terms... or else. He testified to the fact that Scientology is not a religion and the Scientology business is not a church (though Tom Cruise calls this criminal enterprise his "church"). He testified that Scientology has been shrinking since the start of the 1980s.
This video was apparently posted by someone connected with Scientology-Lies.org, but you will notice that the page won't load. Can you say "conspiracy of silence"???
