With a bottle

A shirtless man in grey sweatpants swings a long, thin object at a mannequin dressed in a white karate uniform inside a martial arts studio with red flooring and black punching bags; the man moves in a circular motion, swinging the object around his body. The scene cuts to a group of police officers in a diner, where one officer laughs, then turns to look at another officer with a serious expression as the others react around him.
