Where or what are the Oral Arguments of the case Miranda v. Arizona?

Answer 1

Mail the Supreme court and ask for the records. The oral arguments are the point where the lawyers get to argue their case before th court. Each gets 30 minutes, and the Justices can interrupt at any time and ask questions. They're actually pretty interesting to read, and are public record.

or you can listen to them in MP3 here.
