How to stab?

A man in a white tank top is pushed by a shirtless man in a backyard, then the scene cuts to a man in a green jacket kicking a person lying on the ground in a narrow alley, followed by a close-up of hands using a tool to open a coconut into a glass bowl, then a video game scene where a man in a white tank top is attacked by a police officer on a city street, and the sequence repeats. The setting shifts between an outdoor residential area, a narrow alley, a kitchen, and a video game environment.
