Question:
Who keeps the ring?

1. Post your answer and explanation. Use principles you have learned in my Lecture and Text. This is not based on your opinion alone; your conclusion MUST have a basis in the Law, therefore: YOU MUST refer to the Law and legal principles (say which one(s) and where you found them PRECISELY ("in the Textbook" is not good enough)
2. Comment on a classmate postings.  AGAIN - make reference to the legal principles you have learned in my Lectures, the Text and/or web based resources. YOU MUST SUPPORT YOUR ANSWER BY REFERRING TO ANY OF THESE RESOURCES; AN UNSUPPORTED ANSWER = AN AUTOMATIC "F".  Note: I am not looking for the correct answer (this is NOT Law School)... I just want a coherent answer. Do your best, make an honest effort.
