Whether Miranda creates a permanent, per se bar against all further custodial interrogation after a suspect invokes the right to remain silent.
Holding
No. Miranda does not prohibit all later questioning forever; it requires that the suspect's right to cut off questioning be scrupulously honored.
Reasoning
The Miranda language requiring interrogation to cease when a person indicates a desire to remain silent does not itself specify whether, or when, questioning may later resume. Reading it as a permanent bar on every officer, subject, and future interrogation would go beyond Miranda's purpose and create irrational barriers to legitimate investigation and to a suspect's own ability to make informed choices about speaking.
At the same time, police cannot evade Miranda by merely pausing briefly and then returning to wear down a suspect through repeated questioning. The central protection is the suspect's ability to stop an interrogation. Whether a later statement is admissible therefore turns on whether police respected, or “scrupulously honored,” that exercise of the right to cut off questioning.
