"A non-religious man in Oakland managed to virtually eliminate neighborhood crime with nothing more than a statue of Buddha bought from a local hardware store.
"The neighborhood of 11th Avenue and East 19th Street was formerly a rough part of Oakland, riddled with a variety of illegal activities ranging from littering and vandalization to drug dealing, robberies, prostitution, and assaults. That is until one local, Dan Stevenson, purchased a 60-cm-tall stone statue of Buddha and placed it on the street corner opposite his home. People were constantly dumping mattresses, couches and other junk there, and all kind of shady characters would hang around, so he figured the statue would be an improvement. But, in this case, calling the effect of the statue an improvement would be a gross understatement."
