Should Cardinal Bernard Law Come Back to Boston?

Whether it's true or just a rumor, the new pontiff is said to have had a brief discussion with the former archbishop of Boston, Cardinal Bernard Law.

The rumor, according to the Chicago Sun Times, is that Pope Francis might make Cardinal Law return to Boston for his penance for his involvement in a cover up of the child-sexual abuse scandal within the Catholic Church.

Law was forced into retirement as the archbishop of Boston in 2002, and has been living comfortably in Rome since 2004. Now, should he have to return to the United States, and more importantly Boston, MA to atone for what he had done?
