This story from Narrow Boat World made me think. I thought the idea of using contractors was that it was cheaper than employing your own staff
Weaver police patrols
SO BAD is the vandal situation on the Weaver at Runcorn, that police have mounted patrols on the outskirts of the town to attempt to diminish the problem.
Vandals have also damaged other facilities using power tools and destroyed fencing with cutting equipment.
British Waterways have told police that repeated attacks on its property have reached unaffordable levels, and demanded police patrols.
Even minor damage now needs expensive contractors to repair.
