Although the repeated court cases finished him as a Box Office Star he continued to work behind the camera. However he made powerful enemies include Will Hays, the man behind the Hays Code. For whatever reason Hays had an obsession with Arbuckle and would not let up. In addition the IRS more or less cleaned out Arbuckle and forced him to take on any work he could get.
He was also a hopeless Drunkard and this accelerated his fate.
As regards the original case, it was very much the sort of prurient media coverage that we are so familiar with today. The so-called moral panic was accompanied by salacious revelations.

A tale of moral outrage that ruined a nice guy.
