I only got very sketchy background information about this video, but apparently it’s a CCTV footage of a violent armed robbery of a jewelry store in Saint Petersburg, Russia. As you can see, the robbery was off to a shitty start when the first robber to storm the store slipped and barely regained his composure.
Nevertheless, despite this shaky start, the robbers got off with a decent loot. Stupidly, though, instead of just taking the valuables, they threw them in the bag along with display boxes. So instead of running away with just a small sack full of high value loot, they ended up with a large sack full of worthless display cases mixed with high value goods.
