Pilots with body worn cameras have shown that the use of these camera's by police officers in volatile areas has a clear de-escalating effect, as is shown in a video report by Spiegel Online.
The report shows the Frankfurter chief of police Oliver Hess during a weekend patrol in the nightlife area of Alt Sachsenhausen. He explains to people who ask about the body worn camera on his shoulder how it is used, namely only when incidents take place.
All footage is stored for six months, in cases it is needed for supporting evidence in a criminal investigation or to show if police violence took place. According to Hess, even more important is the de-escalating effect the camera has, even if it isn't in use. People who know they might be filmed, are less prown to use violence.
According to the Hessen ministry of the interior, violence against police officers is now happening far less frequently. Since August, all in all 72 body worn video camera's have been in use with police forces such as in Frankfurt.
