Did your lawyer seriously say that posting this is OK? I'm having really hard time believing that.
In reading it back, I wouldn't say he was enthusiastically pushing it or anything:
"I think you guys have your minds made up. The reality is the risk is probably low. Truth is an absolute defense to defamation. It's unlikely a couple Russians would try to sue you, but you never know. My boring attorney answer is try not to go too far to minimize any risk. Stick to the verifiable facts."
