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.

Answer 1

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

In Duckworth v. Eagan (decided 1989), the Court held that the warnings need not be a verbatim recitation of Miranda so long as the warnings, taken as a whole, reasonably convey the suspect's rights.
