It is unusual for parade horses to bolt (when they get loose, they most often stick with their friends, and otherwise just go home; IIRC their stables are near the palace) and it is unusual for anyone to exercise horses near where people are dropping building materials. Given that an MOD linked MP has given names: Vida, Trojan, Quaker, and Tennyson, as well as their hospitalisation status, I would not want to be the builder responsible.
