HN: NO! free speech.
Sincere advice: get out of those libertarian echo chambers, and think about real consequences.
IF you let LEO's access group chats THEN you absolutely need civilian accountable honest transparent clear oversight to avoid mission creep.
The task isn't as clear cut as "known criminal is part of OC groups", there's a clear Sorities Paradox asking when does an OC group chat become a neighbourhood watch | knitting group chat.
If our criminal of interest is part of RealMafiaChat, PrepperLifeStyles, CamThePolice, GuideDogsForVets, etc. etc. et al. then how many of these should be surveilled .. and how many other group chat members should also be surveilled ?
Yes. Take down real criminals.
Yes, it's an actual problem that real innocents get swept up Kafka-esque for being unwittingly criminal adjacent.
What's the cost benefit number and trade off for actual innocent lives ruined?
I am pretty much against surveillance in the form of drag nets, but none of that applies here. Instead, this is exactly how a functional state should work.
(And note that no exceptions are made for Pavel because he is rich and well-connected. Contrast that with brittle countries where politicians rely on tech billionaires to fund their campaigns.)
I sympathize with you being an Aussie; I can see where your allergy comes from, but in this case it is misplaced.
Yes, functional states should have extremely good oversight .. in reality they "mostly do" but with cracks that allow unwanted behaviours to sneak through and sometimes become normalised.
eg. recent revelations that SASR types are "blooding" new members with unsanctioned kills in war zones. Or regular joe LEO types using surveillance powers to stalk ex's. Or total innocent gets railroaded by tangential "evidence" simply because they chance to tick all the boxes for a needed arrest and the actual perp was overlooked | unseen.
> I would be very concerned if your knitting grandma was an active member of a drugs and arms dealergroup.
And yet an actual sergeant at arms type of an organised biker gang based in Australia used knitting terminology key phrases in just such a group to organise international transfers of "packages".
The person in question was a NZ background stone cold killer with a special forces background.
( Yes, most crims are "dumb" | "lazy" and yet a good few understand covert messaging, not all can be caught with a fake encrypted phone honey net trap )
These are all real concerns and examples of things that have actually happened.
