Thanks very much to the witnesses for being here today.
Mr. Beirness, we've already discussed the per se limits. In putting a number on what a limit would be, it does, as best we can in law, set a clear demarcation point at which the person is impaired or not, or I guess it takes the impairment out of it and actually says scientifically we can show that they've committed an offence because they're over that limit.
I'd like to hear your thoughts on how you see this comparing to the per se limits in alcohol. When those per se limits first came in, was there the same sort of uncertainty about how that would actually be enforced and what that would mean, and whether people would know what .08 would mean? How would you compare that to the per se limits in this proposed legislation?
