Terrorism Bill

: On encryption, it is possible for someone to walk off the street into a store and buy a 192-bit encryption device, which is based on American military technology. Our security services are able to access that technology and counter it. They need the initial period of a few weeks to work out what the code is. I appreciate that the hon. Gentleman keeps referring to the maximum pre-charge detention as three months, but he does not emphasise that that is a maximum. There are weekly reviews. By their own admission, the police do not expect, other than in the most exceptional circumstances, the period of detention to be anywhere near that long. It is entirely misleading not to make it clear that there is constant review throughout the process and that three months is a maximum.
