So, you might be amused to know that the man who built the Pope-mobile for John Paul II's visit to Ireland decades ago spoke about this experience on Irish radio recently, and, a few minutes into the interview http://www.newstalk.com/podcasts/Moncrieff/Highlights_from_Moncrieff/204942/Building_the_Popemobile he speaks about the Pope's bodyguard, Marcinkus, who he describes as carrying a machine gun and being "frightening."
Now, that's what I call a bankster. <lol>
