easy solution:
call the FBI office, give them your side of the story. get lots of people affected by sue scheff to call the FBI, and tell them their side of the story. you're not risking anything unless you lie, or you say something stupid.
i doubt the FBI is taking sue seriously and calling them would further reinforce that notion. I think she ran herself up shit creek by getting the authorities involved, because the FBI is quite thorough, and i really dont think they'd just dissmiss complaints from hundreds of kids and dozens of parents.
i mean...that letter from sue, i dont think anyone could possibly take her seriously after that. she sounds just like a 90 year old woman who's calling the cops on the boogieman in the basement.
