Shark Fins Bill

I am a little concerned about what has just been said about allowing importation for use—for example, in the restaurant trade—provided that it can be shown that the shark was killed for other reasons. To what extent would people be able to check that that was the case, or would they see it as a loophole, and pretend that the shark had died by other means and that they were using the whole carcase? It is odd to me that someone would kill a huge shark just for its fins, but we know that that is mostly what happens. What safeguards will there be to ensure that people do not exploit that rule?
