The only thing I could add is that the one witness who did speak about the technical difficulties that could arise happens to be Corporal Graham, who's observing today, who is the national coordinator of the drug recognition evaluation program for the RCMP. He works with police forces across Canada and is familiar himself, having been an investigator in British Columbia, with many drug-impaired and alcohol-impaired driving cases.
So my only comment or observation would be that he is a highly qualified witness who has spoken to the difficulties that would arise if, at the DRE level, the officers had to have a tape recording. I'm simply trying to point out that he is certainly the most qualified, in my submission to this committee, of all the witnesses who have appeared on this particular subject.
