Israel is not filling its jails for pleasure or profit. On the contrary, it is unpleasurable and expensive to have Pals or anyone else in her prisons. Israel is filling those prisons with persons who seek to harm her and Israelies and that is the way it should be. As to Judge's point of release before there is another kidnapping, what a proposterous point. All the release will do is incentivize Hamas to do more kidnappings. Despite that, the principle has to be to do what is reasonable to get Shalit back.
