Why do Good Cops Defend Bad Cops? [PDF]

open access: yesSSRN Electronic Journal, 2003
Policemen are known to support colleagues who are the subject of criminal investigations. Although we might expect guilty officers to defend each other, why do (otherwise) law‐abiding policemen defend those who have broken the law? We investigate under what conditions it is in the interest of a group to defend its “bad” members.

Good cop, bad cop

open access: yesEducational Management Administration & Leadership, 2016
Research on school principals’ behaviours that affect teachers’ emotional states is limited. Currently, the focus is primarily on extreme manifestations of mistreatment and emotional abuse; normative daily behaviours, such as emotionally manipulative ones, have yet to be explored.
