First of all, you shouldn't be thinking that there aren't any procedures at all taken by the airlines. The airlines have their own procedures. They screen the cargo. Is it screened by a third party agency? None of it is screened by a third party agency. But I think it's important to recognize, as I mentioned before, that the airlines have a very significant vested interest in this process. They have their assets, their employees, their reputation at stake.
