Indeed they should, but all too often people who don't understand the science behind a decision are the ones who make it, especially when the government is involved...

I'll never forget teaching in California when a law was passed (unanimously by both houses and signed into law by Governor Davis) that outlawed "chemicals made from dangerous elements" in science classrooms... Further investigation indicated that "dangerous" included anything "toxic" or "flammable".

Not withstanding the absurd misunderstanding that toxicology is a matter of dosage (and that even water ingested in sufficient amounts is toxic), the ignorance of even middle school level chemistry was quite astounding.

Among the things unintentionally outlawed in California science classrooms: matches, table salt, water, air, humans.
