yes, but what else are those chemicals used for?
potassium fluoride is (per the wikipedia article):
the primary source of the fluoride ion for applications in manufacturing and in chemistry.
sodium fluoride is (per the wikipedia article):
a source of the fluoride ion in diverse applications. Sodium fluoride is less expensive and less hygroscopic than the related salt potassium fluoride.
Both chemicals have a wide range of applications. Here are just some of the uses for potassium fluoride:
used in the metallurgical industry for tin plating and soldering fluxes;
widely used as a catalyst in the manufacture of polyurethanes;
used as ingredient in the manufacture of pesticides and insecticides;
widely used for etching of glass and in disinfectant formulations; and
used in the manufacture of optical glass.
In short, the legitimate, nonviolent uses of potassium fluoride are many and varied, and therefore the mere fact that private companies were licensed to sell potassium fluoride to Syria is not, in and of itself, proof, or even evidence, of evil intent.
