It seems most IED solutions are after the fact detection and/or increasing armor. When I hear about a road called "IED alley", it seems to me that we should be putting as many hidden surveillance resources as possible all over this road. This way we can see the bad guy place his IED follow him and take out his whole network. I realize it would be expensive and not something you could do everywhere all the time, but I have to believe there aren't going to be that many people capable of making IEDs and that we could move on to the next "IED alley" eventually. Let's take the fight to the enemy rather than be pushed by his moves.
