O'Brien was convicted of hit and run, and sentenced to 1000 hours of community service last year; he has been replaced with Bishop Thomas Olmsted who is a good and conservative bishop.
I don't know anything about the money guy you were talking about, but I feel like I just went through a time warp.
I didn't keep up on O'Brien. But the question stands: Why was he subject to the full force of the law, while Marcinkus abides behind boilerplate immunity?
