The hon. Gentleman is absolutely right. A lot of focus to date has been on assaults on police officers, and it is unacceptable that members of the public are spitting at police officers. Nevertheless, prosecutions have been brought for spitting at police officers, but that is almost unheard of in the case of prison officers. Sadly, in many prisons, a culture has emerged of people almost taking that for granted and it does not seem to me that enough priority is given to investigating assaults and other crimes in prison. The police, who are under a lot of pressure with many other things to do, must be encouraged to get into the prisons, gather the evidence and work with the Crown Prosecution Service to prosecute people who assault prison officers. If that does not happen, we will never get the calm, orderly environment that we require.
