Yes, I think it's fairly clear what can and cannot be done. As I've indicated before, we take our undercover operations very seriously, in that operational plans are in place and a very strict framework is placed around the undercover operation in terms of the acts or omissions. They're approved in advance.
For the rare case where an undercover operator finds himself or herself in a situation where something needs to be done, there are exigent circumstances in place that can cover, for example, not having received authorization from a senior official. So there are provisions in place to cover that. And of course there are the three things you cannot do under any circumstances, and those things are very, very clear.
