I won't bother, obviously you "know it all" all ready and have decided that Roush is an idiot, perhaps for following directions of the air traffic controller. Well, thats one man's opinion!
I don't know all the circumstances involved in this incident, therefore, I will not rush to judgement on either side. I would have to assume, from what little we know, that Roush was cleared to land, he made a commitment to do so. Once that commitment was made, circumstances developed forcing an immediate decision.
Who's at fault? Perhaps we will know more as the investigation proceeds.
