Hesse state use of Palantir predictive policing ruled 'unconstitional' 

The German Federal Constitutional Court ruled the use of Palantir surveillance software by police in Hesse and Hamburg as unconstitutional.

German civil rights NGO Gesellschaft für Freiheitsrechte (GFF) argued (in German) that Hesse and Hamburg had not made clear which sources the police could use for obtaining data or how much and on what grounds data mining could be conducted by law enforcement.

Hesse State Police had been using the so-called Hessendata platform, which is based on Gotham. Hessendata reportedly triangulates datasets from police and other databases, including social media, to enable the analysis of potential suspects.

Palantir has also been the subject of controversy in Denmark and the Netherlands over its potential for inaccuracy and ability to reinforce racial and ethnic bias.
