Still not 100% convinced on the applicability under various conditions^[and if I want to be, perhaps I should stop being lazy and go read the law], but I understand it from the Government POV. Kinda similar to the country-country hostage exchange we see in stories, which makes sure the other would have a reason not to renege on some agreement, even if they don't have a reason for mutual trust.
oooooooo
