It always interest me when school professors (college)do research and come up more myth than fact. I lived a stones throw from Scotland Yard's boarded-up headquarters at 2075 Canal Port and knew some of the "Yard Men". Yes, I'M THAT OLD (BORN 1931). The Yard didn't have the man power to halt the operations of the Outfit. R. J. Daley disbanded THE UNIT IN 1956 because they bugged the hotel that had the Democratic headquarters. I guessed he feared "something"?
