Assaults on Emergency Workers (Offences) Bill

I am interested in this fascinating speech. Perhaps to prefigure some of the arguments that will be made from the Dispatch Box, let me say that one issue about increasing the sentence to 24 months is that we would, in effect, be saying that somebody who assaults an emergency worker or police officer receives not twice but four times the maximum sentence that would be received were the attack to be on an “ordinary” victim. Is there not a question of proportionality in terms of the relationship between the equality of citizens in general and their right to be protected as victims, and the special status of a uniformed officer, if it is suggested that an increment of four is better than that of two?
