I don't believe it is staged (many people have died so far), but i also don't believe it's much of a success. From what i've heard only a part of the army was in on the coup so the pro-erdogan side still has plenty of military left to fight for them. Also the video's i've seen seem to show that the military is at least not trying to kill people trying to stop them. People were climbing onto tanks and they could easily have been killed but instead the soldiers try to push them off and scare them off with warning shots.
