I don't know if I have time to add one little thing. In terms of being lawful in the country where it's going to take place, you can imagine the difficulties in the countries I listed earlier. But I just talked about mobility. If we were to obtain a warrant where it would be lawful to do whatever we want to do in Syria, and the next week that person is in Iraq, and the following week that person is elsewhere, again, in terms of, as we say in French,
… “practical”.
I'm not sure how that system would be workable.
