Mr. Colin Connolly:

I have looked at one or two companies. There is a company in the UK called SmartWater, which operates quite an effective system, whereby it is a unique number. However, it does come with a cost element to it and there is an end case element. Ultimately, if something needs to be prosecuted in court, I would always be keeping an eye on the end product. If we do catch somebody with something, we need to be able to prosecute them. The system we have in Ireland is quite robust in that regard in its make-up.
