All I can rely upon, sir, are the experiences we've seen in places where we've had zero tolerance laws. It is very similar to the tandem per se. Tandem per se is a little more specific, and it is directed at impairment rather than simply presence and usage of drugs. That's all I can rely upon.
We have no proof that tandem per se as I've constructed it can be designed legally to meet Canadian standards and challenges or that it can be effective. It's simply thrown out there as an alternative because what is being proposed is not going to work, in my opinion. It seems unfair to simply come in here and say it won't work, and then walk away. I'm trying to offer a usable alternative.
