What does Miranda v. Arizona ensure for a suspect?

The landmark case of Miranda v. Arizona established critical protections for individuals in police custody. It ensures that suspects are informed of their rights before being interrogated, specifically the right to remain silent and the right to legal counsel. This means that any statements made by the suspect during questioning cannot be used against them in court unless they have been made aware of these rights.

This ruling is vital as it helps safeguard against self-incrimination and ensures that suspects have the ability to seek legal advice, which is fundamental to the principle of due process. The requirement for law enforcement to provide this information, often referred to as "Miranda warnings," is a cornerstone of protecting a suspect's rights during the legal process.

The other options do not address the essential protections afforded to suspects in custody under this ruling. For instance, pursuing a plea bargain, denying behavior, or the right to a speedy trial are separate legal concepts that do not directly relate to the specific rights outlined in Miranda v. Arizona.
