Another probably stupid question before I turn in --- from the procession to Westminster Hall.
I know absolutely nothing about horses, so I want to ask why some of the horses suddenly jerk their heads up. This is the horses marching in front of the gun carriage. (Some horses must be pulling it; but I am talking about horses that clearly have riders atop them.) When the camera view is from the front, you see these horses intermittently, and sometimes one after the other, flick their head up really high. I mean a big upward throw of the head. These horses are rigidly trained, I know that -- even outside of a procession like this, these military horses must have a life of being thoroughly trained, so I'm assuming they're not just being unruly or difficult. And I also know the riders aren't just being "mean" to them. So are the riders instructing the horses to do that? Is it a discipline thing? A steering thing? A timing thing? I'm genuinely curious.
