In the investigations of the terrorist act on Drottninggatan in Stockholm and of the double murder at Vår krog & bar at Hisingen outside Gothenburg, surveillance images were a large part of the evidence that led to prosecution and judgment. Since January 1, the police do not need permission to set up cameras. "The surveillance images were absolutely crucial for us in order to reach prosecution," says Johan Axelsson, Gothenburg Police.
