The Proposition was intended by its authors to protect California citizens and the State’s drinking water sources from chemicals known to cause cancer

And having a sign on every building in San Diego does this how?

Well, just like every other liberal program, it doesn’t! You might have also seen those signs in parking garages (like people don’t know that inhaling car fumes for extended periods might not have a negative effect.)

But then again... look at all the good business opportunities those signs created! JOBS!
