When I was an AUSA, Robert Kennedy was Attorney General and began a campaign to shut down the "$1" bettors - he wsn't after me but after the various bookies that took thousands of small bets. So our Sioux Falls, S. Dak. got to work; they knew that a certain cab driver was a local bookie--taking bets on football games (I forget what we called the sheets--I think "Doyle?" but they were always available in the Elks Club. The Feds arrested the Cabbie and found hundreds of the sheets...but they also found names on the sheets that included the U. S. Marshall and many members of the local Elks Club. Unfortunately, we were unable to prosecute when the agents inexplciably lost the tickets.
