Not only that but to be placed in emergency leave status requires Red Cross verification. In addition, the airman was most probably using military space-A in a Category I status (emergency leave) which also requires documentation. There's more to this story that's not being reported IMO. If the commander allowed the airman to just go home in a normal duty status based soley on his account, then he should be relieved and held pecuniary liable for the USAF's transportation costs to send him home.
I don't know about that. It seems that trust would be an important thing, and if he were lieing he would eventually get caught.
That's probably why they were doing a police report to submit to the military. And if he were lieing, which he turned out to be, I'm sure the CO wouldn't want him around anyway. So I don't see how the CO is responsible in any way for being compasionate to his men.
