6.1 The U.S. Constitution and Bill of Rights in Criminal Justice

The U.S. Constitution and Bill of Rights form the backbone of criminal justice in America. They set the rules for how law enforcement can act, what rights accused individuals have, and how the justice system should operate fairly.

These foundational documents continue to shape modern criminal justice practices. From Miranda rights to search warrant requirements, their principles guide everything from police procedures to courtroom conduct, balancing public safety with individual liberties.
