I've noticed that there is a significant interest still in the excommunication of James Hamula, or at least what I had to say about it (click here). I would think that the LDS Church's silence and the silence of the Hamula Family would have ended the matter, but you are directly searching for that specific post of mine.
All we were told is that it wasn't for "Apostasy". It wasn't for adultery because there was no woman connected with Elder Hamula who was likewise excommunicated. And there has been no one to step forward accusing Mr. Hamula of any type of crime. And Elder Hamula would not have thrown in the towel, having had enough of the Church and their cover-ups and lies, for he had been a part of the Church History Dept. and was with the Correlation Dept when ex'd. So therefore there are only two options left for us:
1. The Church outright lied to us. He was excommunicated for Apostasy.
2. The Church is covering up a sin or crime that he committed with a settlement paid to the victim(s) as hush money to keep it covered up.
The Church has a history of doing both of these options. If it were a regular member, unknown in popular society, or even a well known protester, the Church would have issued a public or a congregational statement explaining what happened and why with a warning to members to stay away from the "evil" one. With Elder Lee we learned why, thus the case of James Hamula is very, very disturbing.
