Much in the same way that someone needs to learn how to read and write, understand morse code, or be able to clearly communicate diving gestures.
I think a clearly branded schooling system or team of people or kit that can be sent into communities does a few things;
1. Raises internal awareness of issues
2. Through role-playing, breaks down a potential level of anxiety through fun/play
3. Increases confidence that victims voices can potentially be heard, which subsequently acts as a deterrent to perpetrators.
