SUMMARY - Neighbourhood Watch or Neighbourhood Surveillance?
A neighbourhood watch sign on every corner announces that residents are paying attention, and the burglaries that once plagued the area have declined, the visible signal of community vigilance apparently deterring those who would otherwise have struck. A retired man spends his days watching his street, knowing which cars belong and which do not, which people are residents and which are strangers, and when something seems wrong he calls police, his watching serving as informal surveillance that supplements formal systems.
