Was George H.W. Bush Involved in Assassination of JFK?

[James H. Fetzer]

The original was published in Jesse Curry's JFK ASSASSINATION FILE. A blow-up has been offered that does not look right to me. The detail and clarity of a photo tend to be reduced, often dramatically, when a blow up of a small image occurs, but that does not appear to be the case in this instance. I am therefore skeptical that the "blow up" is not in fact a fabricated image. I only wish that Jack were around to address this question. It doesn't look right.

What is the provenance of the photos in question? Where did they come from? Where were they originally published? Who took them?
