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.
