I don't remember who was City Attorney back in 2006, but I do recall that the F(for fluoride)-bomb was the brain-child of the City Council back then, sometimes fondly recalled as the Worst Council Ever.  

You remember, that was the Council that did all its arguing in private meetings, and always voted unanimously in the public ones.  And the Council that told voters they could either vote for the Taj Mahal of a sports center they had come up with, also in private, or the City would close the Shore pool.  They also signed us up, all on their own, for a ten-year contract with Delta Dental that included a $400,000 penalty if the City stopped fluoridating before the contract's ten-year term was finished.

As to the City Manager  --  we had a different one then, appointed by the Worst Council Ever, and he was a doozy.  Left in a huff after voters broke up the Worst Council  --  easy to do, because that Council had given him quite the golden parachute.
