What is shown is just the very final stage of doctors’ failed efforts to save Mahmoud. I suppose the reason their effort as shown is so gentle is that they have already in effect concluded that it is futile.

How is this a defence against the claim that the doctor was not performing a genuine cpr procedure in the video? It’s actually an affirmation, what he has done here is claim that a little bit of faux cpr is part of normal procedure.
