The saddest thing about this is that when a red coat is injured, it makes the press. When a sab is injured, it rarely does.
Sabs are up in arms at present, following a particularly vile spate of attacks by the hunt, such as running sabs down with quads, on public roads. Running sabs down on horseback, on public roads (shit horsemanship, whether you hunt or not!) and causing injury (and sometimes death) by any means, weapons and tools available to them.
When emergency services (ambulance) try to attend an injured sab, hunts have and will block their access to the injured party, as was the case recently, when a hunter rode down a sab in the southwest.
If sabs are likely to be attacked, some will feel justified in carrying weapons themselves. Sabs are likely to be attacked and far more likely than than a hunt supporter, whip or master.
Why do sabs wear face coverings? Because for thirty odd years or more, the law has fallen down on the side of the hunt. In one particular case back in the 80's, I think it was, a judge found in favour of a hunter, against six eyewitness reports and police evidence from two separate officers!
It's no wonder sabs feel the need to hide from the law when they are regularly let down by the law. Does a red coat have trouble seeing justice done? No! Sabs have fight hard and usually in masse (I.e. protests and petitions), just to have a case of gbh or abh looked at. It's utterly despicable.
