My Lords, I have a confession to make: I love the traffic police. I have spent many happy hours in the front of a police van with an automatic number plate recognition machine, spotting illegal drivers. The fascinating thing about criminals is that not only do they break the law on drugs, guns and so on, but they do not pay insurance on their cars either. If I were a criminal, I would make sure that my car was perfectly legal, but for some reason they do not. So the traffic police are incredibly successful at catching criminals; at one point—I do not know if this is still true—their arrest rate was far higher than that of the average police officer here in London.
In the 12 years that I sat on the police authority, I took advantage of that to go out with the traffic police. I remember one spectacular day when they had a car-crushing machine next to the A1. All the vehicles speeding down the A1 saw that machine and slowed to legal limits. We were not actually crushing cars that had been taken that day; they had brought some cars out with them from central London. So I am a big fan. The traffic OCU serves an incredible function of keeping our roads safe.
I support Amendment 19. Of course, everybody expects the police who respond to blue-light emergencies to drive fast, overtake, go through red lights and so on, and it is right that the police are given the necessary legal protections to do their job in these situations. Then there are more controversial and dangerous tactics, such as officers aggressively ramming moped drivers who refuse to stop. We cannot leave that for the courtroom to decide—it has to be a political decision. Whether a tactic meets the standard of a reasonable and careful constable is political, because you cannot leave police officers uncertain about whether their behaviour is legal. It would also leave the public unsure about what standard of driving you can expect from our public servants. Amendment 19 addresses that issue and is an extremely neat solution.
