It had everything to do with the state's willingness to violently suppress an overwhelmingly effective protest of corporate power. They did so very early in the day on November 30, well before people started to break windows or otherwise target corporate property. I know this in part because I was present at the site of the police's first use of organized violence at Sixth and Union, far from any property destruction. I thought that fluorosilicic acid was composed of fluorine, oxygen, hydrogen, and silicon. Third, you don't give any figure for the amount of fluorosilicic acid added to the water supply, like parts per million.
Fluoridated water is so convenient.
Finally, as a consumer of Seattle water for the last thirty-five years I still am a pretty healthy retiree who appreciates the meticulous care our city water gets. I suggest the excellent summer tour the water department offers.
