Has Robin Hood sold out and now been co-opted by King John as a neo-Sheriff of Nottingham?

Sir, Ralph Atkins and Alex Barker quote Simon Chouffot saying “You can draw parallels between the Sheriff of Nottingham and financial services, and Robin Hood redistributing gains back to those who needed it.”, “Robin Hood tax: A long shot”, May 21.

Sorry but I am utterly confused, I always saw the Sheriff of Nottingham as the tax collector for bad King John, and Robin Hood as providing good people a safe-haven in the Sherwood Forest.
