Hi cookiemaster,
First, Im glad your mom is feeling better! You remain an awesome son in my book and most definitely in hers...
As for the D.A. Just to get technical for a minute. The latest Elders secret book contains a different way for it to be handled than the book before,
If the person capitulated in a moment of weakness or is sorry they are NOT to be dealt with judicially.
Given that, plus the rough way they handled the whole thing, I think you have a really good basis for a law suit if they press ahead.
You wont actually have to go through with it because once the elders call the Org for direction they will be told to drop it.
That way it can be up to your mom if she wants to continue her relationship with this organization or not.
Her choice. As it should be.
