The best part of this controversy is the concern expressed by one of the donkey owners:

Water trader Simon Kamau, who uses donkeys to transport water to his clients utters: “In all the three years I have been in this business, I have never tied a nappy on a donkey.

“The problem is that the donkey can give you a fatal kick. I was once kicked by a donkey and it broke my leg.

“What the council should do is come to us traders and show us how to tie the nappies on the donkeys,” Mr Kamau says

Hmm, Mr Kamau does not mention what he was doing behind his donkey. Maybe he just did not realize the risks. Some large American cities used to be smelled before seen, the saying goes, due to horse droppings and privately managed garbage services. A public control method thus makes sense if the city wants to systematically clean its streets. But it sounds like some donkey training might also be needed…or perhaps regulation with more teeth that would spur more than nappy innovation. Come on Apple, where is your iDonkey? Nice case study of how controls can go awry.
