Re: Glad it's not just me then.
" I have considered contacting the guy by mail, or by phone, it wouldn't be a problem since I've had those details thrust into my lap enough times now, but I'm genuinely scared, since it's clear that he's an idiot, he'll probably decide it's all my fault and set his lawyer on me. It's just not worth the risk."
You said he's "in the states" (wherever that is!), and I assume that you are not. You are out of his jurisdiction, so it's safe for you to contact him, even if he is an idiot who like to make trouble for people trying to help him. If his "lawyer" contacts you, simply ignore it. You tried.
