The "Broken Window" Theory
Think about an old, shut down factory. Someone comes along and throws a rock through a window. How long will it be before all of the windows are smashed out?Experience dictates, not long.
The same theory applies to your neighborhood. If someone paints gang graffiti on a wall and nobody removes it, how long do you think it will be before you see more of it? If someone sells drugs in your neighborhood, and nobody calls the Police, how long will it be before you have a serious drug problem in the area?
If you don't care about your neighborhood, that's where criminals want to be. They like to feel safe to commit crime, and if you don't intervene safe they will feel. Take care of your area. The Police can't do it all. We have to work together. You live here, and we need you to help us keep "here" a nice place to live.
