Maybe he's an honorable man.Why would he quit if he wasn't there?
If so, upon reading all the final reports the right thing to do is admit, at least to yourself, that you didn't do your job of hiring only officers with brains and balls. He may have admitted his training programs, for which he is ultimately responsible, failed prepare his officers to respond properly. In that case, an honorable man would resign.
Maybe he just wants to do the right thing.
I'd like to think so.
