I too have a problem with business models that invade our privacy. But I think it’s a bit disingenuous to conflate “private information” with information that you voluntarily posted on the internet.
Whatever happened to educating people that what they post on the internet is permanent? Dragnets over public data are a symptom of the real problem, which is lack of user education and understanding of what data they generate and share.
What if somebody is arrested and happens to have a very convenient data set on a lot of people, such as data used for marketing purposes. Is it okay if those people are stopped and searched on the basis that somebody else held data about them and the police have supposed that 10% of the clients are suspected of criminality?
Normally there is supposed to be evidence that the crime took place before an investigation can begin.
If law enforcement starts with the evidence and then look for the crime that fits it, that's something different.
Palantir goes to the agency and says, "Give us data and we'll give you "actionable intelligence".
You know, back in the 90s and early 2000s, the term "data mining" was perjorative. Financial operators would look through their mass of data for correlations and sell them to people who would discover that they didn't actually work.
1) yes, the LE do already have the data.
2) agencies don't 'give' data to palantir, law enforcement data almost always lives in air-gapped environments it cannot leave in any way (or only in highly restricted ways)
3) we don't 'give' actionable intelligence, we just provide tools for analysts to generate such data. Palantir is a company of software engineers, not of intelligence analysts.
