Apparently this guy was widely considered to be a crooked judge and had made a lot of enemies. I did a google search and turned up this web page:
Having been through the family court system myself there is a real issue with corrupt judges and how to stop them. In many cases the only way to remove a corrupt judge from the bench is with bullet. I’m not advocationg that, but if you don’t look into this judge’s history you aren’t seeing half of the story. If what all these people are saying about this judge is true it reflects an issue with society that needs to be addressed in order to protect future judges from the same thing.
From what I read here it looks like there were a lot of people who were ready to shoot this judge.
