I can give it a go if you like. Cases of missing children vary widely depending on age and circumstances eg whether or not they ran away from home or were taken on the run by a parent, etc, so a 15 year old who runs away to the big city is different to an 8 year old taken abroad by his father against his estranged mother's wishes, to a 4 year old who disappears from her bed in the middle of the night. I would agree that spending £15 million trying to trace a 15 year old runaway might be considered excessive, however when it comes to trying to find a four year old who may have been abducted, possibly by someone intent on harming her and therefore possibly other children too then £15 million whilst still a huge sum of money seems more justifiable. In this case, if it remains unsolved at £15m then that could be considered money down the drain by some, however spend another (for example £500k) to solve the case, achieve justice and prevent harm coming to others, well then that might be considered money well spent.
