I rather liked that last paragraph about how bad the squid would have tasted. I got the impression of some goggle-eyed young reporter earnestly writing it down.

Unless they are going to be able to do crosschecks at customs to check whether the DNA on the passport is the same as that of the actual travellers (and that just isn't practical), I can't see how this kind of thing is going to have any useful effect whatsoever. But then achieving a useful effect, as opposed to a political impact, isn't what all this kind of thing is about.
