The Manchester book is just that. A book. Id'ing someone based on 2nd hand Hearsay = "young cosmetician" is Exactly how Gary Mack came to wrongly ID McKinnon as the lady on the ground near the Stemmons sign. And that Boner was cavalierly accepted as fact for roughly 30 years. The above is nothing more than once again repeating a bone headed process which the JFK Research Community has repeatedly Proven to be faulty.
Look at the other post I wrote.
We know from what Robinson has told the ARRB and and HSCA investigators, both directly and indirectly, that his job was the cosmetic part.
Also, Robinson confirms Manchester, stating that he rode in with Hagen. Hagen agrees with Manchester that he didn't show up until late.
And Manchester didn't just make up the stuff in his book. He interviewed Powers, Hagen, and two of the Gawlers within about a year of the assassination.
