my inclination is fluoride was probably the most neutral or least harmful to the body when they were looking for something that could be used to neutralize something that may have even been a weapon.  its one of the most critical things to attack when trying to bring down any civilization. because without water everything else comes apart. so whatever must've became an avenue for our enemies to attack people. and we all assume we are being attacked by those who put the fluoride in the water, when it was done defensively and for our protection.  you gotta realize that when it comes to a lot of elitist types, all the various powers that be, to them the end justifies the means. and sometimes the means includes lying to your own people... a lot.
