1. A detective has enough probable cause to arrest Mickey for murder. But before he does, the detective calls Mickey on the phone and tells him, "I'm on my way to your house to arrest you. But before I do, I just want to ask you: did you commit this murder?" Mickey responds, "Yeah, I did. Whadya gonna do about it?" True to his word, the detective goes straight to Mickey's house and arrests him. The prosecutor, at trial, wants to introduce Mickey's statement. One problem: the detective never gave Mickey his Miranda warnings. Admissible or not?
2. A police officer is at a crime scene, and asks, out loud to the assembled masses, "Anybody know who committed this crime?" Willie comes out of the crowd and says, "Yes, officer, I committed it." Willie is immediately arrested. The prosecutor, at trial, wants to introduce Willie's statement. One problem: the detective never gave Willie his Miranda warnings. Admissible or not?
