I don't know Hatefi or Parra, and I certainly don't know the details of the case, so I may be the one commenter here who does not think he knows what the right course of action is.

What I do know is that few of us would have 100 of our customers or clients show up in our defense if we were fired from our jobs. Whatever Hatefi is accused of doing wrong, it's clear he has also been doing something right. Hopefully his possible shortcomings can be corrected.
