At least it was only $1.5 million, unlike some of the dead ends, and hopefully they found stuff about bees/insects they might use later.
I could see there would be a liability of someone getting stung that's allergic to them. Dogs can be leashed, but that's tough with bees. Pretty hard to keep track of the little beggers, too. If they find something, and nobody sees them, boom.
Oh, I know.... they're really going to use them but don't want to tip off the terrorists. Yeah, that's it.... no wasted money. Whew, I feel better.
