Because it wouldn't matter and it would set a horrible precedent. Who's going to define and enforce what a "reasonable expectation of safety" is? The government, who has a revolving door with the same industry it's expected to regulate? I prefer the system we have in place now, which is for the press (alternative, professional or otherwise) to alert people to a problem and they can decide how much risk they're willing to take. Although, I do admit that approach won't work with Monsanto. They don't technically have a monopoly, but they're big enough that a reasonable alternative doesn't exist. But, they're big enough that attempts at regulation or law enforcement won't work either. One of the conundrums of our day, I suppose.
