Fireable offense, yes or no?

From Ananova Quirkies:

Serbian police have admitted they may have accidentally put an explosive device on a plane to London.

It happened after an exercise to test sniffer dogs at Surcin airport in Belgrade went wrong, local daily Blic reported.

Officers had put explosives into luggage destined for Heathrow airport, as well as Paris, Milan, and Athens, and let sniffer dogs loose to find them.

The dogs found all the devices except one before police realised they had not marked the bags and could not find the final package or identify where it was headed.
