Bill Hendon was a rookie North Carolina congressman in 1981 when he heard his first briefing about prisoners of war in Vietnam. Nearly three decades later Hendon still is certain POWs were left behind and he is co-author of a new book he says lays out the proof.
Hendon's position in the book "An Enormous Crime" isn't accepted by government officials and former POWs.
Hendon says declassified intelligence documents show that prisoners were knowingly left at the end of the Vietnam war.
The government says more than 17-hundred American are unaccounted for in Southeast Asia.
