That means nothing to the Pakistani tribal villager or Taliban Joe sitting in a cave in the mountains if they even know there is a reward. What does mean something is if you get an intermedary to talk to Taliaban Joe about about what he wants; more sheep, a couple hundred bucks, a house somewhere to settle down in. And, then have the inbetween guy offer him say a few sheep and some money for providing him info about where say another guy is who Taliban Joe knows is connected to the al-Qaeda and Taliaban leadership. And, then the middle man talks to that guy and sees if he can can be bought to sell out someone higher and if not we pick him up.
That is one way of doing it. Another is the Iranian way they have done in southern Iraq of giving money and food to large numbers of locals in the south in exchange for their loyality and assisstance. We could do that and make several hundred locals our eyes and ears in the area.
That's my point. You're speaking like that's not already taking place. I'm saying it is. But I'll have to go digging for more details, because I don't have any off the top of my head.
