Today, violence is the most urgent threat for millions of the poorest people. According to the United Nations, four billion people live outside the protection of the law. That means that their public justice systems (their police, courts, and laws) are so broken, corrupt and dysfunctional, that there is nothing to shield them from violence. What if you called the police and no one came to help you? Or if there was no way to get justice if someone harmed you or your children? For poor people throughout the developing world there is no defence, no protection, nothing to hold back violence. Over 45 million women, children and men are held as slaves; two million children are exploited in the commercial sex industry. Every day, global justice missions and movements are working together to push back the advance of violence, rescuing individuals and in many cases stopping violence before it starts.
