I have known several retired or former FBI agents (nearby neighbors and/or fellow members of civic club) in years gone by, and they were each great guys whom I liked. All of them were devout Roman Catholics.
They are so disgusted with the FBI that neither one of them admits to any prior involvement with the FBI anymore. One of them says he’s a retired U.S. marshal, and the other says he’s a retired inspector for the U.S. Dept. of Agriculture.
