Yard Ornaments for the 21st Century

In a recent Reuters article, a woman brought in something unusual to the local police; a live hand grenade, still in its packaging.

This brings up two questions:

• Exactly what is the original packaging of a hand grenade? Do they shrink wrap them? Maybe a nice paperboard box with acetate windows to allow the buyer to thoughtfully consider the aesthetic virtues of their proposed anti-personnel device purchase? Does it come in a special bulk-purchase package for warehouse club markets? Does it carry a UPC code?
• In the article, police spokeswoman Patrycia Chalupczynska commented that It is quite unusual for someone to find a grenade in their backyard, especially one that hasn't been spent (bold emphasis mine). This implies that while finding live grenades is rare, finding the fragments of a grenade explosion is rather less so.

I guess this tells me that gang warriors in Edmonton must be utilizing distinctly heavier firepower than the poseurs here in the States.
