BTW, this is considered the leading "resource" on lynching in USA and used by many colleges. My review of it finds there were only two narrow types of crimes that got anyone lynched, and it didn't seem to matter if you were Black or White. Leo was considered not just White, but "bringing jobs to the community". His uncle bankrolled the pencil factory.

Anyways, the two crimes were:

1)Rape and/or Murder of woman or child.

2)Murder of an upstanding citizen in their own home when the murderer and victim had no prior connection.

The only two POSSIBLE exceptions are:

1)mother of a violent Negro who had been killed in a gun battle with police, and she was known to have access to guns and knew how to shoot, and she had vowed to kill police, and/or anyone she felt was connected to her son's death.

2)Teenage Negro who was harassing a White store clerk girl and vowed to rape her when he'd find her outside the store alone.

I find it interesting that even in cases of what we'd call "accessories before and after the fact" anyone who wasn't clearly completely guilty that was caught along with the perp were always instantly released completely unharmed.
Unlike in "official justice" there are no cases of cohesion or forced confessions in lynchings.

Picrel: the last big public lynching in USA was by this Jew when he was in his early 20s. He'd been a child star but his Jewess mom married some Jewish gigolo and blew all his money, but he was still a pretty big star. Other rich college kids his age would be into Sock Hops, frat parties, fast cars, etc, but young Uncle Fester is swinging from street-light pole, whooping up lynch mob in downtown San Jose, CA. How perfect is that? Reason for the lynching was a coupe thugs kidnapped a friend of his and ended up murdering him. https://en.wikipedia.org/wiki/Murder_of_Brooke_Hart_and_the_lynching_of_Thomas_Harold_Thurmond_and_John_M._Holmes
