If these shots are sterlizing people, then it's because the system is failing and cannot continue to support 7B people. Mass depop, through infertility is their plan to prevent future children from being born into a society that cannot feed them. The kings and queens will reign and allow anarchy as long they have the means to provide for their own protection and the future of their bloodlines.
There will be no arrests of "pedovores". They'll simply be denied children to abduct and eat. They feed off the excess, which is being removed by mass depopulation.
