Local information.

Leicester Road is the latest area where Neighbourhood Watch signs are prominently displayed.
This shows any potential 'not so nice' person that the local residents are aware of what they are up to and will make their lives as difficult as possible.
This is achieved by keeping windows and doors locked and keeping valuables out of sight.
A good communication system is set up to keep individual households informed on what is happening in their area.

Vehicles are not excluded from this regime making it not worth breaking a window to pinch any valuables which are now no longer there.
