One more thing to worry about

Evidently, at Charles de Gaulle airport in Paris, it was standard procedure to train explosive-sniffing dogs by actually planting real explosives in a random passenger's luggage.

It all worked well until they lost that random suitcase.

Yes, that method of training has now been banned in Paris. But what if other places still use that method?

I can just see me arriving in London with that random suitcase and trying to explain it all. "No, honest officer, I truly have no idea where that came from."
