My Lords, I agree with the noble Baroness that the hour is late, and therefore I shall be brief. I was here for the debate in Committee on this subject and I was wholly persuaded by the Minister about the undesirability of this amendment. I know full well that Tasers can be very injurious and I know that they are dangerous, but I also know from considerable personal experience that people in psychiatric wards can be extremely dangerous, volatile and violent.
I speak as somebody who was for some years was Minister for the special hospitals. There were three mental hospitals in my consistency. I was the Minister for Police for a time and, relatively recently, I was on the monitoring board of a local prison. I know they are different, but in prisons you see many people who ought to be in psychiatric hospitals. The truth is that sometimes there is no choice: people get possession of a weapon and threaten their nurses or pose a very real threat to the other residents on the ward. What is a police officer to do if summoned and faced with a person with a knife? The truth is that in exceptional cases—which I will come to in a moment—a Taser may be necessary. I am certainly not going to go down the road of prohibiting that by statute.
What does “exceptional circumstances” actually mean? I can tell the noble Baroness: when there is a reasonably founded belief that it is necessary in self-defence or in defence of a third party. If I was the Secretary of State and put that into a statutory instrument, so what? Ultimately, it has to be decided by the court. If you look at this amendment and reflect on its consequences for one moment, the police officer is guilty of assault unless he can bring forward the defence. But who is responsible for bringing forward the defence? Does he has to prove that his acts fall within the exceptional circumstances or does the prosecution have to negate their existence? I suspect the latter, but it is extremely difficult for a police officer in those circumstances. It is a legal minefield and good news for lawyers—which is not something I am advocating in this case. It is a thoroughly bad amendment and I hope we hear no more of it.
