D.M. got rid of his other RTC-Execs Mark Rathbun and Warren McShane
This I learned from Wikipedia about D.M:
"Starting in September of 2005 all mentions of Mark Rathbun and Warren McShane the two other publicly known members of the RTC board of directors were removed from all Scientology web sites leaving David Miscavige as the only member of RTC Board listed on the RTC website.
Reference: Religious Technology Center, Mark Rathbun: Inspector General Religious Technology Center (archive.org copy of RTC.org page from May 3, 2005 - accessed last on June 6, 2006). Compare to the current RTC web site."
