Could be some kind of Kindle deficiency. I'll try on a big pooter.
But then the comparison starts to slip when one considers Ashbys population is mainly resident, and the NECs is transient, often from abroad, and th HMICs own concerns over under reporting. After all, if your car has been screwed will you remain at the NEC until 8am the next morning to see the Dibble?
And does Ashby have a large, dedicated, uniformed security force patrolling? The NEC does, and despite that doesn't compare favourably.
