Ms Velma Burns:

I understand the Chairman's point and I had expected to see a difference across the years but, in fact, if one takes the figure of 38% - which was the overall figure measuring the impact of alcohol in fatal collisions - it was very consistent for every year within that five-year period. It is not like the bulk of those alcohol-related collisions occurred in 2008 and 2009. That was not the case. They were consistent across the years.
