Yes.
In many cases of femicide, some of which even resulted in the death of children, there were risk factors. The most important risk factor is often the presence of past domestic abuse that was not taken into consideration or taken seriously by the police. There are other risk factors, such as depression in a spouse, which is not always considered.
Also, some scientifically recognized risk factors do not always seem to be known by police departments or a number of responders, hence the need for training. We also know that police services will focus on incidents that are recognized as offences. However, domestic or family violence manifests itself in all sorts of ways that, taken in isolation, may seem trivial. That is why we are saying that responders and police need to be trained.
