Most societal problems cannot be fixed entirely. There will always be child sex abuse just like there will always be murder, theft, tax evasion, and drunk driving. It makes sense to see if things can be improved, but any action proposed must be weighed against its downsides. Continued action by police is a good thing, but laws for that have been established for a long time, and the correct answer may well be that no further change to laws is required or appropriate.
(Ab)using child sex abuse to push through surveillance overreach is particularly egregious considering that by all objective accounts most of it seems to happen in the real world among friends and family, without any connection to the internet.
