Reading Mr. Wright's "Looming Tower" on the rise of al-Qaeda. It's good. One interesting side note is John O'Neill, the retired FBI agent who died on 9/11 who was quite a character. Wright mentions that Italians and Irish predominated in the ranks of the FBI. I wonder why and when? Was it from the beginning or was it after J. Edgar?
Perhaps it was a generational thing: the sons of policemen who went to college wanted to follow in the steps of their fathers and do law enforcement. Perhaps it was a prejudice thing in that early graduates of Catholic law schools (Fordham, Notre Dame?) found it easier to get admitted to the FBI than to existing WASP law firms?
