Wow...it's hard to believe the timing on that one. It's definitely an example of how the U.S. fails to function on even a minimal level when it comes to preventing IPCA. This parent was "lucky" enough to be aware of the risk, had sole custody, and even in this situation, there is no means for identifying these children before they travel and preventing it if they are not with the custodial parent or there is a custody case pending. Too many parents, unaware of their spouse's plans, would not be helped by such a system, but it should definitely be put in place for those who would.
