The Dangers of "Chocolate"

I watched with amusement last night's news item on the French airport police who lost a chocolate-sized package of plastic explosive. Seems they were testing their sniffer-dog's capacities, placed the explosives in someone's luggage - but couldn't retrieve it before it was removed from the conveyor and flown off to destinations unknown!

The French are left with red faces and an international appeal on TV.

I wonder if the person who finds this in their bag will know what it is, and that it can take out an entire house. I wonder if they'll think they just have a bad memory and can't remember putting it there themselves. I wonder where it will turn up! I wonder if it will turn up at all...
