Residents in Surrey and Kent villages have been ordered by police to remove wire mesh from their windows as burglars could be injured.
The doctrine here is that dead men file no lawsuits. If I had to install hardware cloth over my windows to keep the local lowlifes out, and the police informed me that one of the choirboys might sue me if he was injured trying to break through my defenses, I think I'd amp up the defenses a bit.
In England, standard wall current is 220V, and hardware cloth is conductive. I had often thought that a decent living might be made for an enterprising fellow with a discreet cleanup service too.
