There is a difficulty in linking matters like this to performance and numbers. We saw that with the breathalyser numbers. People were pressurised to produce results. I would also like to focus on the logic of this. The idea underpinning the spending of this money is that it is preventative. Its success is not measured in massive returns to the coffers of the State. It is probably a healthy thing if the amount we are spending is more than the yield, with the caveat that it needs to be an accurate depiction of what is happening on the roads. It would make sense in those circumstances. If there was a suggestion of something improper in the awarding of the contract, I could see that we could investigate it, but other than that-----
