Who would have guessed this would turn out poorly?
His weight is behind him and he’s not leaning into the recoil.
Every shot, every time, you need to think about whether your have good footing, nothing between you and your target, and of course, personnel protective gear.
So there are lots of things wrong here.
No PPE, a bystander that appears to be off to the left and in front of the shooter – what happens if he started to fall and then pulled the trigger?
Then, of course, the fact that the shooter is in a horrible position to actually take a shot – and paid for it.
