Charlie, Mrs Roberts said that the jacket she saw Lee putting on was a DARK COLORED jacket.....This was a spontaneous statement by Mrs Roberts. And I'd agree that "tan" is not a dark color.... But WHERE did you get "tan" from Mrs Roberts statement, that the jacket that she saw Lee putting on was DARK colored.
These are the words that Hugh Aynesworth wrote regarding what Roberts told him on 11/22/63:
“He just ran in his room, got a short tan coat, and ran back out.”
