An extract for above:
A police constable who reached 159mph on a motorway has been cleared of speeding and dangerous driving.
Pc Mark Milton, 38, from Telford, Shropshire, was recorded by the patrol car's video camera on the M54 in 2003, Ludlow Magistrates' Court heard.
District Judge Bruce Morgan acquitted him after calling the constable the "creme de la creme" of police drivers.
Pc Milton is trained in advanced driving and was "familiarising" himself with a new car, the court was told.

But the Police Federation defended the driving of Pc Milton, who is also known to have travelled at 120mph in a 60mph zone and at more than 60mph in a 30mph zone.
Outrageous.
