This 1994 documentary was never supposed to be seen, and upon viewing you will understand why it was to be destroyed. Fortunately someone kept a rough copy of the documentary and leaked it a year later.

A message from Senator John Decamp:

In mid-1993, after The Franklin Cover-Up had been circulating for almost a year, the British-based TV station, Yorkshire Television, sent a top-notch team to Nebraska to launch its own investigation of the Franklin case. Yorkshire had a contract with the Discovery Channel to produce a documentary on the case for American television.

Finally, the big day came. Their documentary was to air nation-wide on the Discovery Channel on May 3, 1994. It was advertised in the TV Guide and in newspapers for that day. But no one ever saw that program. At the last minute, and without explanation, it was pulled from the air. It was not shown then, and has never been broadcast anywhere since.

I have a copy of that program, which arrived anonymously in my mail in late 1995. When I watched this pirated copy, I could see clearly why the program had been suppressed. Conspiracy of Silence proved, beyond doubt, that the essential points I had stressed in the book (and more) were all true.
