Executive Summary

German police authorities are increasingly using AI-powered analysis software from Palantir for data evaluation in investigations. The system promises faster investigations in serious crimes and terrorism, but faces significant data protection and political concerns. Bavaria and other federal states have already introduced software variants, while the federal level is seeking alternatives and critical oversight questions remain unresolved.

German police authorities are increasingly relying on Palantir software to link various police databases—a trend that accelerates investigations into terrorism and mass shootings, but simultaneously carries massive data protection and control risks. The Federal Constitutional Court declared parts of the practice in Hesse unconstitutional in 2023. The central tension: While investigators demand faster access to more data, data protection officers and legal experts warn against uncontrolled mass surveillance by private US defense contractors.

Detailed Summary

The software Vera (Bavaria), Hessen Data (Hesse), and DAR (North Rhine-Westphalia) are variants of Palantir systems that automatically consolidate information from various police data sources. Criminal Senior Inspector Jan Deggebrot from the Bavarian State Criminal Police Office describes concrete operational gains: in acute threat situations (attacks, mass shootings, terrorism), investigators can determine within minutes rather than hours whether a single perpetrator or multiple offenders are involved—critical for deployment tactics and public safety. Since September 2024, Vera has been used approximately 140 times in Bavaria.

However: Bavaria has explicitly not activated AI modules. According to the Police Tasks Act, self-learning systems, automated conclusions, and internet connectivity are prohibited. This makes the software significantly less powerful than its US variant used by US Immigration and Customs Enforcement, which extensively uses mobile phone data, social media monitoring, and facial recognition.

The Federal Constitutional Court made clear in 2023: databases may not be linked arbitrarily. The fundamental right to informational self-determination requires purpose limitation—data collected for terrorism investigations cannot be searched for car thefts. In Hesse, such boundaries were exceeded; the legal situation remains tense. North Rhine-Westphalia reported in 2025 that over 2,000 officers had used the software—without clear documentation of whether this was constitutional.

Baden-Württemberg approved Vera in 2025 as a "transitional solution" until 2030, then plans to switch to European systems. Critics like Konstanze Kurz (Chaos Computer Club) criticize a new experimental clause in the police law: agency data may henceforth be used for AI training by commercial providers—originally not collected for this purpose.

Key Points

  • Efficiency Gains Confirmed: Vera software demonstrably reduces investigation time in serious crimes; Jan Deggebrot cites specific mass shooting and attack cases.
  • Bavaria Blocks AI: While Palantir offers AI modules, Bavaria uses only manual data linking—a German security boundary that other federal states do not consistently maintain.
  • Constitutional Court Sets Limits: The Federal Constitutional Court in 2023 prohibited undifferentiated data collection; Hesse and North Rhine-Westphalia partially violated these requirements.
  • Dependency Trap Grows: 39 million euros in North Rhine-Westphalia for hardware, software, training. Exit becomes a tanker problem; Palantir effectively becomes non-replaceable.
  • Political Contradiction: Federal states preach digital sovereignty but continue Palantir contracts. Federal level under SPD Justice Minister Hubig stops federal deployment; CDU Interior Minister Dobrindt explores it anew.
  • US Defense Contractor as Partner Controversial: Peter Thiel and Alex Karp of Palantir are considered skeptical of democracy; publicist Marina Weissband calls the company "designed for total surveillance."

Critical Questions

  1. (a) Data Evidence: Vera was used 140 times in Bavaria since September 2024—but how many of these uses resulted in legally binding convictions or would not have occurred without Vera? To date, there is no independent success rate analysis.

  2. (a) Transparency of Interfaces: Palantir does not disclose what mathematical patterns the software recognizes when matching databases. How can courts verify whether algorithms work constitutionally if the source code remains secret?

  3. (b) Manufacturer Conflict of Interest: Palantir profits from every license fee and has an incentive to portray the software as indispensable. Who independently determines whether German or European open-source alternatives function similarly?

  4. (b) Control of Control: In North Rhine-Westphalia, 2,000+ officers used Vera without documented access criteria. Who regularly verifies that only investigators with appropriate suspicion access the software?

  5. (c) Causality in Prevention: Hesse attributes terrorism prevention in 2018 to Hessen Data. Could another method (classical database query, telephone surveillance) have achieved the same result? The counterfactual is missing.

  6. (d) Abuse Risk During Power Shifts: If a party like the AfD were to hold interior ministries in eastern Germany in the future, Vera-like software could be directed against journalists or opposition figures. Are technical safeguards in place?

  7. (d) Baden-Württemberg's Experimental Clause: Permission to use police data for AI training was introduced without consulting affected parties. Can supervisory boards legally "extract" this data again if courts later invalidate the clause?

  8. (d) European Alternatives Mature? The mentioned systems (Almato, One Data, Secunet, Unite) have not yet been tested on a larger scale. How realistic is Baden-Württemberg's plan to switch to European software by 2030 without millions in migration costs?

Additional Reports
