When seven German journalist students do a better job of tracking down the sources of the drone flights over Europe than the security services...
Stephan Eggermont@davep that doesn’t seem to what happened. They say they got non-public security service information in which they acted. Bild is the ideal target for these kind of deliberate actions by security services. Zero depth, and excellent sensation pushing
@StOnSoftware It may include an attempt by the security services to get more budget for their teams and surveillance drones.
