Hampshire Horsewatch have volunteers who patrol local villages for a minimum of 8 hours a month, to help keep rural communities safe. They wear hi-viz jackets, and the horses are kitted out in protective clothing. The volunteers cant arrest anyone, they have to report to police, anything suspicious (poaching, fly tipping, sheep rustling!) I only know this because I recently saw this and googled it. I live in North Hants, but I don't know if this is common in all rural areas. Good idea I think.
