Malathion Spraying and Cancer Risk

Malathion. Pesticides. Herbicides. Poisons! How can anyone prove conclusively one way or the other whether a poison is carcinogenic or not when the effects cannot be known for tens of years later, like the effects of radiation? And when the variables are so many that no one can put them in any one test tube?

Why insist on the illusion of conclusive proof when common sense is enough. And who ever gave the power to declare martial law to the state Department of Food and Agriculture?
