When police are revealed to have killed an unarmed suspect or used excessive force during arrest, police generally defend those actions. Cops who report wrongdoing are routinely ostracized as “rats” and denied promotions, according to a 1998 Human Rights Watch study. Researchers identify this so-called “blue wall of silence” – the refusal to “snitch” on other officers – as a defining feature of U.S. cop culture today.
U.S. military culture stresses organizational, rather than personal, loyalty.
And the pride Marines famously feel, for instance, comes from being part of this well-respected corps. Personal relationships with other Marines are of secondary importance.
