Dr Hubert Winston Smith was Jack Ruby’s lawyer after he fired Melvin Belli (Ruby’s first trial lawyer). Dr Smith was Ruby’s lawyer for the retrial you talked about earlier. Apparently, Ruby’s lawyer had known of and possibly previously worked with this psych doctor. His lawyer MAY have brought him into the case to set up an insanity defense. That’s generally why lawyers bring psych doctors into a case. Ruby didn’t have much of a defense. He shot and killed Ruby in front of about 20 reporters, half a dozen cops and on live television. Insanity was probably his best options.
I found the link you posted earlier after
@beardown07 first posted about this psych doctor. It was Ruby’s lawyer who brought this guy into Ruby’s case.
Joe Rogan had an interview with a guy who wrote an entire book about this psyche doctor. Here’s a portion of that interview.
