The problem is, there is no way to prove the tires needed more testing. All 4 samples could have been treated in the same fashion. Also, the original story was that 6 were tested and 4 failed, now the story is morphing into all of them failed. So the answer is, enforce the rules as written, and come up with a contingency plan for second sets of samples if you believe you have a genuine issue. Yes teams that got busted lose money and are angry, but a new policy is put in place to solve the problem. Or you can do what was done, and this leaves people wondering if it is all above board, or did shenanigans occur. That suspicion of shenanigans will never go away.
