Crapper snappers

The other day I was walking to a meeting and in a bit of a hurry, and stood in a pile of dog poo. It was disgusting and the smell still hangs around my shoes, even though I have washed them. As there is a number to call to inform the council about illegal fly tipping if you see a car or van doing it, a similar system could be set up for naughty dog walkers. However the evidence will be harder to prove preventing it from being pursued in the criminal courts. So I propose the setting up of a naming and shaming programme. It would work something like this, a person sees a dog walker not picking up their dog's poo, takes a picture of him and the dog and the offending evidence. These pictures are then sent to an email address or texted to a number and posters of the offender are posted up around the park or public area, declaring their crime. Out of shame they might stop their nasty habits, or switch their walking path out of embarrassment, eliminating them from the area anyway.
