David49, let’s not muddy the waters, we aren’t talking about a random dog bite. In any event that isn’t simple. If a person is bitten by a dog because there’s a dog fight, the police aren’t interested.
If you prod, poke, get in the face of a dog and it snaps, don’t you carry responsibility. My dogs insurance covers legal costs, I’m certain if one of my dogs had reacted after being treated as these horses (and their riders are) my insurers would defend any nonsense claim.
It isn’t “all just for show”. It’s a glorious continuation of some of our odd, eccentric and very `English traditions. Long May it continue. Paint a red line, use those scary armed police officers to get the crowds to keep a sensible, safe distance
Not everything is the responsibility of everyone else.
