This bit gets me:
"Derbyshire Police said no official complaints had been made but said there have been previous incidents where tacks were placed on roads in and around some villages.
"Anyone acting in this manner is putting people at serious risk of injury and, potentially, even death. It is not just cyclists that could be affected - horses and their riders, walkers and other trail users could all be hurt," the force said"
As if to say, injuring horses, their riders, and walkers is bad, but injuring cyclists is in some way understandable.
I'm sure it's not what they meant (I hope it's not what they meant), but I wish they would bloody well learn how to choose their words more carefully.
