Was your friend a staff member or an oldcomer at the time? Did this happen in his home while it was being used as a host home?
Let me tell you something, any time a person accuses someone of abuse that person gets defensive and seeks to attack the credibility of the accuser. So what would you have a survivor do just shut up about being abused to avoid having their credibility attacked? If you had been abused don't you think your friend would be pissed at those responsible and lash out against them?
Anyway don't worry about the credibility of AARC survivors that speakout, they have over 4 decades of proof of the same damn thing happening to others.
Here's some homework, if you truly care, Read the
Blueprints - some good news articles in there.
I can only hope to help you understand the nature of this beast. Not knowing what incident you are talking about, I can't help you with that directly. Just know that horrible things happened in the host homes, things that your friend, being a good and honest person, would be very ashamed to admit having any part in.
The survivors that post here do not make accusations lightly especially against other kids that suffered along with them. Think about it. 10 years later and this person says that your friend had some hand in abusing them!?! What reason does this person have to lie, they can't get any justice. On the other hand your friend would face great shame if these allegations are true, and thus has a good reason to lie.
