There was other data given in the presentation which Deputy Catherine Murphy and others have questioned, about people with blood alcohol levels under 50 mg and between 21 mg and 50 mg. I am still confused by that evidence and I think it is undermining the witnesses' case. If I felt one life could be saved by making whatever reduction, I would support it. However, I have not heard conclusive evidence or explanation as to why there are more deaths between 21 mg and 50 mg.

The witness has mentioned more time and so on but if drivers are detected with levels of 35 mg or 40 mg and there have been more deaths as a result, that would offer proof but that bridge has not been crossed by the witnesses. We talk about educating people. However, the lack of conclusive evidence undermines the witnesses' case.
