Certainly, we are going to have to have regulations for both national and international levels. There will be some delay, but that is what will happen one day. We have not yet determined, on a national scale, the people to whom the requirement for security clearance would apply. But we want to keep this power in case it were decided that people transporting explosives must have a security clearance. We want to keep the door open, but no policy, no regulations and no firm positions are in place.
