What was established in Maryland v. Shatzer regarding breaks in custody?

In Maryland v. Shatzer, the ruling clarified the impact of a break in custody on the assumption of coercion that often accompanies police interrogations. The court concluded that if a suspect has been released from custody for a significant period of time and then taken back into custody for questioning, the circumstances are such that the coercive pressures of interrogation that may have existed initially have dissipated. This means that the suspect is considered to have regained the ability to make a voluntary and informed choice regarding whether to speak with law enforcement.

Therefore, the correct understanding is that a break in custody removes the presumption of coercion that can otherwise render statements inadmissible. In essence, the ruling recognizes that time away from custody allows for a fresh start in the context of interrogation, meaning the suspect's statements can be treated differently compared to immediate follow-ups without a break. Statements made after such a break could be viewed as more voluntary and less influenced by the pressures of prior custodial questioning.
