Are or were there POW's left behind in Vietnam???

Back in the late 1970s and 1980s, there were a number of movies and books written about how many Americans who were POW's in the Vietnam war were left behind after the war ended.

In the early 1990s, the Senate set up a committee chaired by John Kerry to look into the matter. The conclusion the Kerry committee came up with is there was no basis to the charges that POW's were left behind.

Sydney H. Schanberg at the Village Voice is taking issue on this and is damning Kerry for his conclusions and the way Schanberg says the committee operated. Schanberg is claiming Kerry lied and colluded with the Executive Branch to suppress the truth. Schanberg, obviously, did and still believes the US left people behind and some could still be alive.

It's surprising to me that the Village Voice is aiming its guns at Kerry like this. Will be interesting to see if anyone else picks up the story, although personally I am inclined to discount the Schanberg's view at this time.
