Great! To be clear by "interview" I did not mean interrogate, I simply think it's a great idea to have a chance to talk with someone from the PPA, and it would make OP's friend feel more at ease I'm sure. We all might also get to have a clearer view of what happened.
Please offer this to your friend, OP, this is very important to a lot of people including you and your friend.
Thanks again and look forward to this.
