Its one thing when a news organization decides not to show a video for editorial reasons -- its quite another when you go to the Internet and virtually all of the sources that come up with the major search engines have an edited-down version of the original video -- some of these edited-down versions include the title "FULL VIDEO" and show only the most horrific finale where the pilot is being turned into a crispy critter.
I took a look at the original by downloading its torrent (they haven't gotten around to suppressing that yet the way Hollywood suppresses downloading of their movies via torrents). The things that seem to be actually suppressed on the internet (as well as news organizations) are not the horrific scenes of the pilot burning, but rather 1) the horrific scenes of children/infants mutilated by the bombings, 2) the "testimony" of the doomed pilot describing the details of the bombing operation, and 3) the list of pilots, upon each of which ISIS has placed a 100 dinar bounty.
