Effective policing requires that crime witnesses and victims contact the police and that citizens trust law enforcement. Without such trust and communication crimes go unsolved, criminals run free, and victims live in fear. Sadly, it looks as if the Trump administration’s immigration rhetoric could have prompted a chilling effect on Latino crime reporting.
The father of modern policing, the British statesman Sir Robert Peel, understood how important public approval of the police is in order for police officers to effectively do their jobs. Peel founded London’s Metropolitan Police Force in 1829. The force issued new officers with copies of “General Instructions,” which included the “Peelian Principles” of effective policing.* The second Peelian principle urges officers
To recognise always that the power of the police to fulfil their functions and duties is dependent on public approval of their existence, actions and behaviour and on their ability to secure and maintain public respect.
Although written for officers in London, the Peelian Principles migrated to the states, where now former New York Police Department Commissioner William J. Bratton featured them on his blog and they continue to be favorably cited by law enforcement and public safety officials.
