Actually, i have sent him another 2 tougher ones in Q&A format, but have got nothing back yet until i shoot off an email to him quoting the IS reply. I guess IS's reply is something made PL jump up and down from another Lawyer's perspective and finally decided to respond.

In his defense, i think he is not in the position to give any further comments or opinions other than those ones that have gone publically...

my suggestion, just try to keep the questions open to the level where he might feel easy and safe to answer.
