I work security at a nightclub and about two months ago, I was at work on a saturday night. A guy we had quietly ushered out for the evening due to being drunk came back and started an argument at the entrance. He swung at my coworker so I took him down. We're on the ground and he's got a whole handful of my shirt. I tell him to let go, he punches me in the face. I grip him by the neck and press my thumb into his adams apple while I begin hammerfisting his face. His face opens up and blood gets everywhere. He rolls and I go with him, eventually ending up on his back. He tries to put my foot in an ankle lock but I grab his hair and slap him in the face with my palm. He keeps struggling so with my hand still gripping his hair, I drive his face into the tile floor. I hear a crack and he stops moving. The cops arrive, get a statement and EMTs place him on stretcher. I get another shirt from the office and go back to work. I feel nothing for what I did to him. I feel no remorse and I lost no sleep.
