"Police corruption is ubiquitous and is a serious problem for numerous reasons. One is that police officers are often armed and can therefore pose a physical threat to citizens in a way that most other state officials do not. Another is that citizens typically expect the police to uphold the law and be the “final port of call” in fighting crime, including that of other state officials: if law enforcement officers cannot be trusted, most citizens have nowhere else to turn when seeking justice... According to Transparency International’s 2017 Global Corruption Barometer, more people pay bribes to law enforcement officers globally than to any other public officials, rendering the police the most corrupt branch of the state in many countries."
