 Andrews testified to the Warren Commission that the reason he told the FBI this was because of FBI harassment.In his book, "On the Trail of the Assassins", Garrison says that after a long search of the New Orleans French Quarter, his staff was informed by the bartender at the tavern "Cosimo's" that "Clay Bertrand" was the alias that Clay Shaw used.According to Garrison, the bartender felt it was no big secret and "my men began encountering one person after another in the French Quarter who confirmed that it was common knowledge that 'Clay Bertrand' was the name Clay Shaw went by."
