What is the key ruling in Miranda v. Arizona?

The key ruling in Miranda v. Arizona centers on the requirement that accused individuals must be informed of their constitutional rights, specifically the right to remain silent and the right to an attorney. This ruling emerged from the case involving Ernesto Miranda, who confessed to crimes without being informed of his rights against self-incrimination or his right to legal counsel. The Supreme Court determined that to protect the Fifth Amendment rights of individuals in police custody, law enforcement must provide a warning to ensure that suspects are aware of their rights before being interrogated. This ruling established the now-famous "Miranda Rights," which law enforcement officers must recite during arrest to inform suspects of their entitlements, thereby safeguarding against involuntary self-incrimination.
