With respect to section 172.2, it does require that reasonable steps be taken, which isn't much different from some of the provisions we have now with regard to the age of consent. The courts have outlined what those reasonable steps are. I do think that the reversal of onuses will attract constitutional litigation. I don't think it's the most problematic part of the legislation.
Your question about entrapment is very interesting, because of course the cases that deal with entrapment don't allow police or the authorities to randomly approach people for no reason and suggest things to them. If that's the road we're going down, there definitely will be challenges. Those challenges for entrapment arise after the trial process, so it's a very resource-intensive process.
We're getting close to the area where that seems to be a possible outcome for there to be random virtue testing on people to see if they'll engage in the conduct or not. The courts have found that's not acceptable, and that has yet to be legislated away by the government at this point.
