Violence could have declined because people are becoming better, or it could just be a desire to not get caught by cameras that are so cheap and planted everywhere by private entities. Caring for the poor is a nice gesture, but if you don't believe the average person will do all they can to help the poor; The only option you will be left with is to form a government that will care for the poor(Provide Justice). As a poor person, I can assure you that the organizations to help the poor are far less helpful than the individuals who help us out.
