the man abandoned his post. He deserted. It's not really a matter of debate, it's what he physically did.
There have been multiple investigations into this, dude, and the case file on him is thick as crap. It's been examined ad nauseum, as have any reports of his movements or activities.My argument is that you only have what you hear, and don't know if what you hear is accurate, or if there is information you don't have. Nothing has been confirmed, supported, or examined.
