Yeah Arnie's credibility suffered due to the same circumstances as the rest of us. His life, like many of our lives, became disrupted by and dominated by all things Scientology. When "wogs" were scrambling to get credentials we sat on our duffs studying Scn only to find ourselves way behind when we finally bit the bullet and got out. Lots of us are exceptionally competent in our fields but never went out and got all the official credentials. I only managed to get a measly Associates degree many years later just because I didn't want to just have a pile of wasted college credits so I went back and tidied it up into a general associates degree.
