If you took out a calculator, added up some numbers, and hit "equals," you'd expect an answer that was indisputable, right?
Now imagine there were certain buttons on the calculator that would make the math turn out differently. Or suppose you and a friend just agreed the calculator's result was flawed and from now on you'd tweak it. Or suppose the two of you couldn't even agree on what numbers to enter into the calculator.
If all of that was the case... would you use that process to spend as much as $50 billion in taxpayer money? No? Then read no further... because you're not going to like what's after the jump.
