This video features a short segment on Clarke. He appears at 14:00, behind Gerry Armstrong. The segment continues to 18:12:
Here's Clarke years later as a retired CCHR President and a spokesman for CCHR:
IMO, Marty Rathbun's "compassion" is 90% PR.
I recall his "compassion" towards Heber J., and I recall also the derogatory statement he made about Heber shortly afterwards.
If Hana Whitfield, or Gerry Armstrong, or Paulette Cooper were to need help, would Marty step up? (Or at least make a big display of appearing to step up to help?). I doubt it very much.
Marty is using Clarke, just as the CofS did.
I suspect that Marty's 'compassion' is largely motivated by PR needs too. After watching the videos you posted, I came across this photo, which I believe to be the same person. It's a bit fuzzy, but it looks like the same guy.
I do feel sorry for the guy, but only a bit. I hope things go better for him, but if they don't I won't cry.
