Best Gore member @mouloudo explains the backstory thus:
This is a photo from Notre Dame des Landes in France, where some black bloc idiot thought it was a smart move to pick up a grenade thrown by the gendarmerie mobile ( anti riot force) to throw it back. Photo taken this Monday.
Some people are settling in the french country to protest against the building of a new airport, the french cops are currently trying to expel them.
Also the take on the story by Best Gore member @nalul:
This happened in “Notre Dame des Landes” near NANTES in FRANCE where rioters (unemployed antifa public money sucker) fight against an airport project. They already won, and the French government abandoned the project a few month ago. But rioters think because they defend the construction place, they own the land.
Rioters were reported using Molotov cocktails, gas bombs, nails traps, acid filled bottles, etc and throwing them at the French gendarmerie, who defended themselves with teargas grenades.
One of the rioters thought he was some kind of superhuman invincible to the detonation of the grenade. A cop sent a teargas grenade their way to break up the rioters. This one picked it up to hurl it back to the cops. Best idea ever.
