The news that an OSINT researcher spent 30 minutes to find a fugitive that the German police couldn’t find in the past 30 years says a lot about how government works here.
Most likely the police would say that they couldn’t use any modern tools or data sources here because of Datenschutz (data protection) reasons. Datenschutz is 1. a great excuse for people who don’t want to do their jobs and 2. a way to protect every kind of crook and criminal.
