When is a Confession Not Admissible in Federal Court?

          Federal Rule of Criminal Procedure 5 states in part that "[a] person making an arrest within the United States must take the defendant without unnecessary delay before a magistrate judge, . . ., unless a statute provides otherwise."

          But what happens if the police violate this rule and the arrested person confesses to committing a crime after he is arrested but before he is taken before a judge?  An article that I posted on my Federal Criminal Lawyer website looks at the U.S. Supreme Court case of Corley v. United States which addresses this question.
