Another article in the New York Times had this interesting description:
The letter was also signed by Raymond L. Flynn, a former ambassador to the Vatican who now leads the Catholic Alliance, a national Roman Catholic political organization.
He was also the mayor of Boston for nine years. I wonder why that fact was left out. Maybe it is because it doesn't mesh well with the hed of the piece"Two Conservatives Tell Bush They Oppose Plan for Police". It's just a bit odd that they overlooked his mayoral career.
