"In my judgment it matters not whether the push was lawful or unlawful in determining the answer to the question whether the appellant was wilfully obstructing P.C. Upshon in the execution of his duty. The push clearly had no bearing on the question whether the appellant's conduct before that time amounted to wilful obstruction. On the findings of the magistrates it did. I am unable to see how an unlawful push could retrospectively render conduct lawful, which was otherwise criminal. But equally, if the push were unlawful it does not follow that P.C. Upshon was any the less acting in the course of the execution of his duty thereafter in dealing with the arrested man in the car. Even on that hypothesis, a person who has been assaulted by a police officer is not liberated from the application of the criminal law prohibiting wilful obstruction of a constable (including that constable) in the execution of his duty. The assault itself could not be characterised as being part of the execution of the officer's duty. That is why Fraser Wood was entitled to resist when he was restrained . . ."
"An offence of common assault or battery that is committed against an emergency worker lawfully acting in the exercise of functions as such a worker . . ."
". . . an assault on any individual or citizen in our society is a terrible thing, but an assault on an emergency worker is an assault on us all. These people are our constituted representatives. They protect society and deliver services on our behalf, therefore, an attack on them is an attack on us and on the state, and it should be punished more severely than an attack simply on an individual victim."
