BA,
I am sorry for what you are going through. You need to reel yourself in a bit. I don't say that to be cold, but honestly, you are holding some pretty important cards. I keep on hearing you say they are going to label you insane or mentally incompetant. Well first of all, everyone here has been labeled that by them by default. So you must be in good company. Second, who cares what they label you. You cannot be disfellowshipped for "gossip" by telling people what happened to you and who it was that did it.
The craziest thing about this, is that if for some reason you got disfellowshipped for warning others about this mans behavior, you would have the law suit of all law suits. The branch will not let that happen. If you have this on record, went to the police, and there was a comitte meeting (you said he confessed it right?), then you have all of the ammo.
So now it just depends on what you want to do with it. We here would love for you to make a big splash, tell the media, wait until he is appointed, get the branch involved, and just go nuts on them with your emotions in control and a goal.
But maybe that isn't what is best for you. Maybe you need to make sure he isn't apointed, tell the police what is going on, and be very firm with the brothers. If the elders are coming by asking you if you would be hurt if he was appointed, take their calls and let them in. Tell them yes. Show them stats on these things as being recurring when someone is messing with a child. Explain JW's are already in the news left and right about these things, and why would they be going through such pains to make sure he is in a position where he could do harm?
Don't run from it. Run to it........if you can stand it. If you can't, then find a way to cope, say your peace, and decide what it is you really want. :)
