Case 21: "empty warehouse"

Very gruesome video where a ragtag bunch of militia men partially wearing fatigues and hoodies as well as tracksuits stab an agonising bound man, then mutilate and finally shoot him.
One of the perpetrators wears a noticeable black hoodie with green inscriptions on the back (the logo on the back mentions "but", which can also designate a (football-) goal in french).
