I choose to believe.

Who are these scientists who spend all day thinking of the best way to help athletes cheat? Wasn't EPO and CERA the bi-product of medical research? I can't belive that there are scientists sitting in labs researching the best way to help Usain run faster and be undetectable by the governing bodies. It's too cloak and dagger.

Surely the world doesn't work this way.

This sounds eerily like what many cycling fans said in the 1990s. Loving their sport they simply did not want to believe that it was riddled with drugs, specifically EPO, though the evidence was clear by 95. The Festina scandal of 98 opened a lot of eyes: it did not stop the drug taking. Only the most rigorous testing and, in the last two years, the threat that cycling would lose all it's sponsors - and the riders their jobs - have really had an effect.
Athletics is years and years behind. Just look at the physical shape of sprinters now compared with the 60s; they have classic steroid-users looks. Cycling fans have come to spot the dopers pretty easily: avoid out of competition tests, have dodgy doctors or trainers 'preparing' them, be part of a small training group who all perform above expectation, win their races by unlikely margins.
There is money in winning; doping doctors like Ferrari took a cut of 'their' riders' winnings. The world works exactly that way.
