How do police get away with police brutality?

Answer:
This is a very old problem; even in the Roman Empire, the question was famously asked, who guards the guardians? Since it is the police who enforce the laws, it is the police who have to arrest other police officers in the event of police brutality, and quite often, the police stick together. Police don't like to arrest their fellow police.
