Question

in duckworth v. eagan (1988), the supreme court held that the police
had been too harshly burdened by the miranda decision and no longer had to follow it.
could create their own miranda warning if it communicated the same message.
did not need to read the miranda warning if they considered a suspect to be dangerous.
could create any warning they chose so long as they got a conviction.

Explanation:

Duckworth v. Eagan (1988) centered on the flexibility of Miranda warnings. The Supreme Court ruled that law enforcement does not have to use exact, standardized Miranda wording, as long as the warning effectively conveys the core Miranda rights (right to silence, right to an attorney, including court-appointed counsel if indigent) to the suspect.

Answer:

could create their own Miranda warning if it communicated the same message.
