I was thinking more along the lines of targetting of political dissidents, building unlawful programs, arresting people on the basis of information not lawfully collected, and so on.
The Snowden revelations brought this topic up when it comes to US intelligence abroad, but I don't think such violations ever occured inside the US. (or respective western countries, say).
Or let's go old school. Remember good ole' J. Edgar Hoover? Even before the digital age, the man created enough waves through amplified access via HUMINT that cast a pallor of doubt over decades of politics.
There is absolutely no rational reasoning to endorse further centralization to enable systemic abuse. No privileged system will remain free of abuse in the face of those seeking ultimate power. The only way to prevent those seeking it from finding it is to identify the power grab when it happens, and shut it down.
I absolutely do not condone the Four Horsemen of the Infocalypse, but let me be clear; a world with pervasive and perfect surveillance is a world where the machinery, if left alone to it's own devices inevitably tends toward the destruction of our humanity.
I know the religious language may not carry As much weight for some, but I think in this rare case it's the most concise way I can make my point. As sinners, we are born, through forgiveness, repentance, and redemption we grow and cultivate that which as a species is said to entail all that which is generally regarded as being beautiful, and virtuous about us. Part of that, as a societal unit, comes in the form of fighting the most vile amongst us without abandoning the moral high ground.
We don't have police procedures and the rules around dispensing justice because we want above all else to punish criminals; if we were really out to do that, just point the mob of the majority at everyone they disagree with or deem a criminal and 'let God sort it out' as the most ruthlessly pragmatic would say.
On the contrary, though; we make it so hard to police, we constrain acceptable methods of investigation, because at some level we all understand the violence inherent to the system, and the inevitability of the occasional employment of it. We rein it that we may in some manner drive it, and live not in constant fear of those that drive it; as they too are (supposed to be) bound by it's laws.
It should strike a tone of alarm in anyone when those acting as the executors of the system's mandates begin fighting to loosen the rein. In no case does that bode well for anyone involved left unchecked.
