Query: Convincing investigative work

I always thought that the B20 story was a little bit fictitious and Michael Asher puts forward a convincing logic to his story. If you read his findings you'll start to see holes appear in McNab's and Ryan's versions. By Asher's accounts, these men have already disgraced the regiment by bad-mouthing a fallen comrade and lied about/embellished the rest.Asher goes back to the LUP, where the whole cock-up begins, and then traces the supposed journey all the way through to its conclusion by talking to local people who were present at the time. Unless the whole of the Iraqi people were there to spin a yarn, it's hard to deny that the truth is not what is in the other books. There is no disgrace in the truth.
