According to a study, bodycams can not greatly reduce violence. However, there are reasons that speak for their use.
That's what it's about: Police officers from Zurich and police officers must be equipped with body cameras, so-called bodycams. This was announced by security officer Karin Rykart of Zurich after the heavy attacks on police officers during the weekend. With Bodycams rioters could be tracked down and convicted, so the hope. Zurich would be the first canton that Bodycams would use. Other cantons consider it.
Possible effects: Dirk Baier, head of the Institute for Delinquency and Crime Prevention at the University of Zurich, has accompanied a pilot project by the Zurich police. He does not believe that bodycams would greatly reduce violence against the police. "Our study has not given strong arguments," he says.
The study did not provide Bodycams with powerful arguments to reduce such incidents that we experienced during the weekend.
"Not even that they reduce such incidents as we experienced during the weekend." Nonetheless, the study suggested that Bodycams of police officers and police experience a lot of acceptance. "This is because they promise to collect good evidence," explains Baier. The existing film images can be played in court, so that the statements of the police are accepted earlier.
Necessary requirements: To introduce Bodycams, according to Baier, it is absolutely necessary to establish clear rules. "Rules that determine which people within the police have access to this material and when the material will be removed." The point is to warn the police: "We do not want to control your work, but to make it easier, and there are certain rules for that."
Thin knowledge situation: The effect of Bodycams has so far been little research. Baier regrets that: "As a scientist you would always like to have good arguments for the introduction of new measures." On the other hand, the demands on the Bodycams were also slightly increased.
This is the right step to give the police a means that can facilitate their service.
You have never asked for empirical evidence for other sources. Bodycams is now required. "At the same time, we only have to deal with a small video camera and this should suddenly reduce the amount of violence," he criticizes. The ZHAW teacher still finds it good to enter the Bodycams. "Not necessarily to reduce violence, but to give the police a means that can simplify their services."
