Devo makes a good point on how the EU should outlaw such activity. But, Dario rightly says that it is up to the soverign government to act on such laws in its own country. Why wait for a government to act? Usually, the process is challenged along the way and likely nothing ever gets done. We have hare coursing in Ireland. The laws governing coursing have changed since the 1970's when hares were more often killed than not during each event. Today our coursing demands that the greyhounds wear muzzles and the frightened-out-of-their-wits hares survive every time but probably with some kind of psychiatric problems. The hares are supposed to be released to the wild after each meeting, but in practice does this happen? Nobody knows. Furthermore, non performing greyhounds find themselves on an express route to the knackers too to save expense. It's all about the money.
But, hare coursing in Ireland is dying a slow death. Lack of sponsors, lack of support, lack of the will to make a meeting worthwhile etc have ensured that one of these days soon there will be no hare coursing, of that there is no doubt.
