For the second time in only a few days a major motorway has been closed for several hours whilst the police and other agencies deal with some "suspicious" material left on the motorway.
The thinking behind the actions of these agencies must be that these materials are somehow dangerous and planted for a purpose - improvised explosive devices (IOD). That must be what drives these operations. They obviously have a duty to protect the public, but.... The country, its people and businesses need these roads open, and open as soon as possible.
I can see no possible reason why the roads cannot be temporarily closed, Bomb Disposal to go in, use the robot to drag the "object" into the open, carry out a controlled explosion, sweep the crap off the road and get things moving again. If it was an IOD then forensics will offer clues, if it was a bag or rags some charity shop is going short for things to put on the 50p rack.
It does not really matter, we need the roads open and opened in short order.
The way things are currently being dealt with it would only take a handful of "devices" to be placed at strategic points on the motorway network to bring the whole country to a standstill.
