It was not his job to watch out and report valid concerns to the Ministry. He would have oped the Ministry was already aware of what was happening - especially as the group wasn't exactly a secret.

Your earlier comments indicated this meeting was a personal matter and given your brother's extra-curricular activities that would make sense.

"However, if you are indeed here for more professional matters then I suggest you start by posing your first question."
