This document discusses the role of police in society and some of the ethical issues they may face. It provides two examples of police misconduct - in one case officers planted drugs and lied after killing an innocent woman in a botched drug raid, and in another officers were accused of committing perjury in drug bust reports. The document also discusses the tremendous power police have, and how even with professional standards and codes of ethics, some officers may abuse that power or engage in "noble cause corruption" by using unethical means to catch criminals. It explores the tension between seeing the police role as "crime fighters" versus "public servants".
