> Despite the lack of evidence to show the effectiveness of location data to stop the spread of the virus, a number of countries’ governments have used the crisis to introduce completely new surveillance powers or extend old ones to new COVID-related purposes.
Some US states will use smartphones for opt-in contact tracing using iOS 13.5+ and Android 6.0+, https://9to5mac.com/2020/05/21/covid-19-exposure-notificatio...
> Alabama, South Carolina, and North Dakota are among the first U.S. states to express interest in Apple and Google’s Exposure Notifications API for assisting COVID-19 contact tracing.
It is not yet understood if/how state health contact databases will be combined with other county, state or federal databases, but Palantir manages multiple databases and is involved in both US and UK Covid-related data fusion projects, https://techcrunch.com/2020/05/20/palantir-covid-19-va-contr... & https://tech.newstatesman.com/coronavirus/palantir-covid19-d...

#5Current theory isn't about missing connections between people. With social networks big and small, everyone can be connected to everyone else. Thanks to twitter I'd bet the US president isn't more than a hop or two from every terrorist suspect on the planet. (Not trying to be political, making a point about connected people.)
So the existence of "links" no longer matter as there are links between everyone. What matters is the quality and content of those links. It starts with bi-directionality. Sure, the president's twitter feed is read by terrorists but do they also speak back to him? Then does he reply? That back-and-forth would represent a higher-order of connection. Are they speaking publicly? How many people are in on these conversations? A private conversation matters more than a public back-and-forth twitter war.
A machine mining a database for raw connections isn't useful. To judge the quality of connections you really do need a human mind capable of making a judgement call. They need to put the connection into context. Or, since it's all encrypted and they cannot do that anymore, everyone is linked to everyone. A warrant can be got for anyone anywhere. Send in the killbots when and where the boss wants.

#6Old hat. Phone records are almost an anachronism. Current theory isn't about missing connections between people. With social networks big and small, everyone can be connected to everyone else.

I dislike the premise behind "it's all encrypted and we cannot do that anymore" since we have no idea what capabilities an agency like NSA has now or could have in the future. If their capabilities grow perhaps they can replay all that saved encrypted data from their Utah Data Center and throw it into AI for analysis. Why do you assume a human has to be involved in the judgement process for it to be taking place?

Everything being discussed in the context of leaks is by definition in the past. Use them to inform your understanding of the NSA mindset, not your understanding of current events. "Phone" is just an obsolete pre-2010s term here for the exact kind of pattern analysis you're describing. I dislike the premise behind "it's all encrypted and we cannot do that anymore" since we have no idea what capabilities an agency lik…
I don't. A human is not necessary to the process. A human is necessary for the process to be done well. And if the NSA has broken its own encryption, to the extent that it can read past traffic, call the IMU because there are some Field's medals that need handing out.

#9>> “Cheney ordered that Stellarwind be concealed from the judges of the FISA Court and from members of the intelligence committees in Congress.” (a) Anyone able to expand on the author’s source for this; (b) what if any US legal guidance at the time enabled this; (c) and if anything between now and then has changed legally.
Then the onus is on people outside that circle to learn, investigate and prosecute, which could take years, or never.
Sounds bizarre, but it's a real thing:

#10At what point do we assert what we have known for years; that aggregted metadata is by its nature unethically privacy-invasive, and detrimental to human rights?
