Society has a mindset of its own & violence seems to be it's leading cause.

Since January 2011, statistics shows that it's only been 10 homicides in the city of Newark, NJ alone. Usually it's more then 10 murders within a month. That means, the violence in Newark has decreased 20% lesser then usual. But, keep in mind it's still 9 more months in this year left. What  are some of the things that can be done to keep this percentage the same for the rest of the year?
