Throwing a milkshake on Nigel Farage wasn't assault either, because actually, for all the milkshake thrower knew, Nigel may have doused himself in petrol before leaving that morning and he might have had a lighter in his pocket, ready to turn himself into a terrifying human fireball, running around the streets grabbing innocent civilians in a firey frenzy. Had that been the case, then NOT throwing the milkshake on him to neutralise the accelerant could have resulted in many deaths.

You just never know.
