I don't think that's as big a concern in the U.S., but they do have concerns about expert testimony, as we do in Canada. Trying to get an expert is certainly an uphill battle. I was quite surprised in doing the work in the U.S. and then looking at our results in Canada. It seemed that even though our systems are very different, there is a vast amount of similarity.
I've spent the last nine years working with the different practitioners in Canada and the U.S., and I can honestly say I've never met a practitioner who was not concerned about impaired driving. They're all concerned; they're just looking for ways to be more effective in what they're doing and to keep that specific and general deterrent effect out there.
