It's something that can't be fixed, so rather than trying to cure it through bad privacy invading laws we should be looking in how to mitigate the problem through good reporting, accountability laws, and therapy laws.
A few examples of how mitigate the problem
* Require 2 adults at all times when kids are involved. Particularly in churches and schools.
* Establish mandatory reporting. None of this BS like "I'm a priest, I shouldn't have to report confessionals." That sort of religious exemption is BS.
* Make therapy for pedophiles either fully subsidized or at least partially subsidized.
* Require adult supervision of teens with kids (one of the more common sources of child sexual abuse).
CSAM will happen. It's terrible and what's worse is even if the privacy invasion laws could 100% prevent that sort of content from being produce, that just raises the price of the product and pushes it to be off shored. No amount of chat control will stop someone from importing the material via a thumbdrive in the mail.
The problem we have is the truth of "this will happen no matter the laws passed". That truth has allowed politicians to justify passing extreme laws for small but horrific problems.
This is a way more sick proposal of authoritarianism than any law that would allow cops to read chat messages with a warrant.
Which part exactly?
