Interesting interview, but Ted Braden was not Cooper. He doesn't fit the description and profile. Braden clearly had the skills and was a badass but he looked like one as well, he had a very unique look. His hair was receding and straight, not curly/wavy/marceled. He had blue eyes. Stews told the sketch artist Cooper had a protruding lower lip, Braden did not. Cooper got giddy when he got the money, a badass like Braden wouldn't have. Cooper was not a hardened badass soldier, he was military but not a real tough guy.
Other than being a badass with skills there is no evidence for Braden and he doesn't match the description/profile.
Some of these suspects are unique people with great stories that elevate them within the Cooper discourse.. but that doesn't make them Cooper.
