Blue wall of silence

The blue wall of silence,^[1] also blue code^[2] and blue shield,^[3] are terms used to denote the informal code of silence among police officers in the United States not to report on a colleague's errors, misconducts, or crimes, especially as related to police brutality in the United States.^[4] If questioned about an incident of alleged misconduct involving another officer (e.g., during the course of an official inquiry), while following the code, the officer being questioned would perjure themselves by feigning ignorance of another officer's wrongdoing.
