Minorities in the criminal justice system 2015, para. 19
Paragraph
Paragraph text
Police often have wide-ranging discretionary powers. Some discretion may be necessary owing to the nature of their work. However, the broader the discretion, the greater the risk of its arbitrary or discriminatory exercise, particularly in the absence of effective independent oversight mechanisms. Indeed, globally, and specifically in such areas as counter-terrorism legislation where police powers continue to expand beyond the reach of effective oversight mechanisms, minorities are increasingly at risk.
