I can't really answer your question, either, from an enforcement perspective. In general terms, I suspect there is more on-road enforcement in the U.S.
Is it more effective? I can't answer that question. All I know is what my members might say to me, which is that they're going to comply with the U.S. law, because if they don't, who knows what might happen. So they are more fearful, I think, of the U.S. enforcement agency. But is it any more effective? I don't know.
In this particular area, I think they're over-regulated. I really will say that: I think they're over-regulated. I think there are some dangerous goods they do not need to regulate from a security perspective. Those goods need to be regulated from a danger to health, danger to environment perspective, but they don't need to be regulated from a security perspective.
But as you know, all of these regulations were developed in the cauldron of 9/11, without very much sober second thought, I'm afraid I have to say.
