Of all of the tragedies and casualties of the intifada, in which more than 4,000 people were killed over five years, the case of Rachel Corrie still stands apart, the subject of intense world interest and fierce debate... Part of it starts with us. ""They had no business being there"" is no excuse for what the Pentagon long ago christened collateral damage. We've learned much. But we're still not there. We should have saved Rachel Corrie's life that day, either by sending out a spotter or delaying the bulldozer's work. Right now, somewhere in the West Bank, there's an eight-year-old whose life could be saved next week, if we've managed to learn the lesson and are resourceful enough to know how to apply it.
