Even if Pope Francis does not make the change in canon law, may individual confessors require the penitent to turn himself in to the authorities as a condition for absolution?  I remember a similar question in high school religion class -- the question was about someone who committed murder.  I might be remembering incorrectly, but it seems to me that the priest who was teaching the class replied that the confessor could, and that he would, require the murderer to surrender as a condition for absolution.
