Your privacy diminished, again

So we’ve just given in to the American demands for flight data.

Now, I can just about see why they’d want to know the names of people coming into their country, but they get that anyway when they look at your passport, along with DOB, a photograph of you, and currently biometrics of you as well. Why on earth they need to know whether you ate the fish or the chicken, or your credit card number, on the other hand… Isn’t that just overkill?
