I don't know that it would weaken enforcement, necessarily. I think there are bigger problems with addressing spills. Who's paying for them? Who's liable for them? We have a big problem with both the national and international liability insurance funds. They don't actually cover the costs that would result from a significant spill, whether it's on land or on the coast. We have one happening right now, and taxpayers are going to end up with a lot of the cost of cleanup. And remember, cleanup is not possible for a lot of those types of spills. It's a huge risk that no amount of enforcement or safety enhancements can effectively address.
