I thank my hon. Friend for his message.
Let me finish this point about the future tech. We have not really touched on the internet of things, and that global connectivity of billions and billions of devices. That might have an impact on the way the police and other services investigate a crime.
I read a simple but odd thing about how electronic doorbells can play a part in crime. Apparently—I hope no one is listening to this—burglars can observe the data usage when a doorbell is rung and an internet connection is established with the owner, who may be at
work or away. The fact that the data usage rockets up tells the burglar that the person has not come to the door and that they are observing what is going on from afar, and so are not there.
