Disinformation put out by the government is the easiest and cheapest way to pacify the masses.

All you need to do is put out what looks like a credible study and make people question what they have heard and confuse them a bit, and a movement loses a LOT of momentum.

I hope not too many people are fooled by this though, a 2 year study is just not enough time. But at least they admitted that mercury levels in the urine were higher, and I bet the statistics if we were given them would speak for themselves!
