The Law of Unintended Consequences.
Stuff all of what has been enforced has been thought through.
Take for example the Council in the Hawkes Bay shutting down the camping ground they own. THEN setting up a place for campers to park in a car park with no water and no toilets!
Some people in camping grounds are long stayers I.e. it is their HOME!
Great for big stables to put all their horses out but as you point put they are just shifting the problem and no doubt the liability.
Not many of those with their new found powers that they can now wield from their living room are doing systems thinking and answering What If.
Also who is going to end up in jail or lose their license if their horse while doing light exercise breaks into a gallop?
Yet they are expected to be put out fresh into a paddock where they can gallop their hearts out which they are trained to do and naturally want to do. I bet their will be more injured horses to deal with.
One lesson I see from all this is that those countries that followed a test, test, test policy straight away have got on top of it. That should be a message to the those in charge that that is the way to control drug abuse in horses and people in the industry.
