Perhaps I can make one comment.
You said that barely 40% result in convictions. The numbers I've seen are higher than that. A lot of cases don't go to trial; the person pleads guilty. So maybe it's only 40% of those going to trial.
As for what in this bill will bring that number up, well, we certainly believe the DRE is very solid and will help there. And we have the evidence to the contrary defence, making that defence a rational scientific defence instead of making it based upon hypothetical calculations of what the person's blood alcohol would have been.
So we are hopeful that this will lead to a higher conviction rate in those matters that are currently going to trial based upon the toxicologist and “me and my three drinking buddies” kind of evidence.
