White Helmets fake their videos, as proven by Swedish Doctors for Human Rights.
White Helmets are regularly discredited by pro-Kremlin outlets, see e.g. Disinformation Review Issue 51 http://bit.ly/2hinv4F and 52 http://bit.ly/2hKdAIx. Furthermore, "Swedish Doctors for Human Rights" is a small group of people who on their website supports numerous pro-Kremlin disinformation narratives e.g. the one about MH17 http://bit.ly/2oHYTIX.
