That is true when:
- there is enough people still on the street that can do the surveillance.
Or when there is enough social control
- when this people on the street has enough citizen responsibility and not
just laugh and look in an other direction.

When one of this factors is not there, you got the other side effect because
the criminal can easy and fast doing what he want to do without been
noticed. He just wait until there is nobody to see and in less then a minute
it is mostly fixed.

According to a report from an Arkansas television station, street
lighting reduces crime.

The report quotes a Springdale, Arkansas police officer as saying that
"studies show anywhere from 12% on up to 50%" reductions in crime that
occurs. He goes on to explain that "the presence of lights in a
neighborhood increases the natural surveillance of the area."
