I couldn't disagree with you more!
But personally, I can't see any "sport" in prolonging the chase of a wild animal, whether that's a hare, a fox or a driven pheasant!
Get in close and kill quickly and cleanly is the best sport, in my opinion. And if that means walking up to a hare in the beam of a lamp before slipping the dog, then that's the best way, imo.
So, while I do not condone illegal coursing in any shape or form, or even legal coursing, to say that killing a hare with a dog "breaches all of the sporting decency rules that I and I hope many on here hold dear to their hearts", as you did in post #13, I think needs challenging.
There's nothing wrong with killing a hare with a dog if the chase is short and the death is quick. There's lot's wrong with hunting a hare with a dog if the chase is deliberately prolonged for the purpose of "sport" and gambling.
