So you're now saying the HSCA was right to call Shaw a "highly paid" CIA source?
The HSCA never said that. The "highly paid" business comes from J. Kenneth McDonald, a CIA historian, in response to an HSCA request. What has never been seen is the documentation that caused McDonald to make this statement. It is my understanding that the collection (or box or whatever) that McDonald susposedly got this information from is available. But, so far, no one has produced such a document.
Now maybe someday it will come out that Shaw assisted the CIA beyond his Domestic Contacts interviews. I doubt it, but anything is possible. Until then, all we have is McDonald's statement. Of course, that is good enough for most CTs including the "journalist" Morley.
