You know, the problem with any government that promotes a "law and order" agenda is that they originate it from the eyes of policing. Justice never enters the picture.
What that government wants is compliance from citizens at the most base level. You will obey and comply with the demands and requirements of the police. The courts never enter the picture.
In a just society the police are not the appliers of justice. That comes from the courts. In a just society, the police are witnesses in the process of the application of justice. In that regard, they possess no greater power than any other citizen, because the courts of a just society will not allow it.
Decide what you want, because any government which promotes itself as a "law and order" regime has no interest in justice.
