Query: Publisher should be ashamed

The publishers of any Stephen Ambrose book should be called out for printing his work. He was not a credible historian. He was a known liar and plagiarist. He was known to completely fabricate his work. He finally got exposed for the fake that he was, yet people still read his work believing they are reading the real story. His work is not believable.
