Evidence that CNN video is fake: women at grave site
Charles Johnson and some of the comments point out a number of problems with the video, including the shoddy re-enactment of CPR and the fact that the attending doctor is an open advocate of Hamas (and the 9/11 hijackers).
There is an additional piece of evidence: the presence of women at the funeral procession and the grave, visible towards the end of the clip.
Islamic funerals are restricted to men only. I have seen several Muslim funerals—I used to live near a Muslim cemetery—and the barring of women from funerals is one of the many complaints raised by Muslim feminists such as Nadia Davids.
It seems almost certain to me that this video is a fake.
