How do you define torture is also tricky, some nations only consider putting you on a rack and using thumb screws to be torture, while waterboarding and rape is considered enhanced interview-techniques.

Others are even more ruthless like the gulf monarchies that will blatantly subject you to medieval torture.

However the surveillance capeabilities give opportunities for torture that fly under the radar. For example the eastern german dictatorship used a wide network of spies/human intelligence and paid snitches to gather information that was then used to desintegrate a person, by manipulating their life through orchestrated social and professional failures. Spreading rumors that are not easily disprovable. And so forth. Knowledge is power and I suspect that while the eastern german stasi methods would not be used in a democracy. I also suspect that these methods once developed wont go away as easily. I also suspect that more nefarious methods exist that we the public haven’t caught on to yet.
