Here is a propaganda video put together by ISIS featuring John Cantile as the investigative reporter. This is the same John Cantile who was kidnapped with James Foley and “remains a hostage” according to most news sources.
In the video we see a couple of things:
White Helmets operating exclusively in ISIS controlled areas and at the direction of ISIS.
White Helmet uniforms, helmets, and signs in a bombed out ISIS headquarters building.
