There is absolutely no excuse for assaulting any kind of emergency worker, whether one is on drink or drugs or completely sober. I have to confess that I do not comprehend what goes on in the twisted mind of someone who would commit an assault, particularly on somebody in an ambulance who is coming to the medical aid of a fellow citizen. My hon. Friend raises a good point about aggravating factors. When we shortly consider, hopefully, the doubling of the sentence in legislation, I will certainly take that into account. The Sentencing Council is about to start a review of the sentencing of assault, and I urge him and others to make a submission to that forum as to aggravating factors.
