Life certainly means life

Couple of things strike me about this story concerning the man who set the bombs at the 1996 Atlanta Olympics.

First is the obvious hypocrisy and confusion shown by a ‘pro life’ campaigner who was so dedicated to the ‘pro life’ cause that he killed two people. But his sentence is even more baffling. He has been given four life sentences AND 120 years. Is the additional 120 years in case he rises again after dying four times? Or are the life sentences a hedge against him living beyond the next 120 years?
