Excrement happens, I suppose.
Spoiler :
I was going to post that I realised I finally gained serious nerd cred by managing to watch a Star Wars film before Sommerswerd did, but if it's her last it's bittersweet.
I think it's more so that there's no real reason to leave it. We know he should, but by all accounts from an Imperial perspective he's peachy keen with nothing to worry about. He didn't know the scope of the weakness, only that there was one (potentially).
Yeah, that is what I mean. Krennic is in Scarif for a reason, and Tarkin just deletes all data and evidence the hard way. He doesnt even bother getting anyone to investigate. His failure is not to not flee the Death Star, it is to go mucking about with it when the security breach has not been fixed yet.
Spoiler :AFAIK, there was no time for an investigation. The events that transpired between Scarif and Yavin IV take place over a week, maybe? Two weeks at the most. It's unlikely Tarkin would oversee an investigation given that crushing the rebellion is finally a thing that's happening. Plus, he has to play with his new toy. If we're making canon assumptions here, I would imagine that the investigation was given to ISB (Imperial Security Bureau) to contend with. Due to the rag tag nature of the mission and the fact that the major players are all dead, it's unlikely anything fruitful would come from an investigation anyways.
Spoiler :
Tarkin had better prove that obliterating a fortress that actually withstood a powerful assault and destroying all the troops, ships, AT-A(C)Ts, ordnance and other very valuable resources along with it was in some way necessary or at least that his successes (destroying the rebel strongholds of Alderaan, Yavin, potentially Dantooine) outweighed it. Of course, he didn't.
Just by not unleashing a cataclysm upon the face of the planet Tarkin would have allowed an investigation to take place… am I right to suppose that the Death Star attacks Yavin without a destroyer escort? I didn't see any other ships except the rather small wing of PIE fighters led by Vader.
