If the glove don't fit ----

I came across a short dated 1932 on a DVD,* Frisco Jenny / Midnight Mary*, where the detective released a murder suspect because the bloody glove found at the scene of the crime was too small. What are the chances, would you conjecture, that the defendants lawyers in the OJ murder trial knew that this was out there?

Heck, what are the odds that Superman’s first case would be to uncover the true killer of Jack Kennedy? In 1938, yet!
