Final answer:
The key criminal justice rights, including Mapp (exclusionary rule), Miranda, Gideon, and Furman, are explained here.
Step-by-step explanation:
The key criminal justice rights that you asked about are Mapp (exclusionary rule), Miranda, Gideon, and Furman.
The Mapp case established the exclusionary rule, which prohibits the use of illegally obtained evidence in court. Miranda rights, named after the Miranda v. Arizona case, ensure that suspects are informed of their rights to remain silent and have an attorney present during police questioning.
In the Gideon v. Wainwright case, the right to counsel was extended to felony cases, meaning that individuals facing serious charges have a right to legal representation. Furman v. Georgia questioned the constitutionality of the death penalty, leading to a temporary moratorium on executions in the United States.
