Imagine for a moment that every policeman in Britain were issued with two or three tracking devices, each the size of a small packet of chewing gum. Magnetically attached to a car, it would record the target’s every movement for 48 hours using its inbuilt GPS. When retrieved and plugged into a computer, it would plot the places visited by the suspect as a line on Google earth.

Now imagine the same device equipped with a simple SIM card and mobile phone transmitter. A little larger now, perhaps the size of a small matchbox, the device can be programmed to send a text to a pre-assigned number revealing its position, speed and direction of travel. Send a simple SMS code and it might reply with *00015.6716,E,5108.3743,N,8.87,338.42*060909,151948.000** to reveal that it is at location 000°15.6716’E and 51°08.3743’N travelling at 8.87mph at a bearing of 338° on 6 September at 15:19 GMT.

Now before the police were issued with this kind of thing, one would imagine a fairly extensive debate.
