Counter-Terrorism and Security Bill

The hon. Lady has produced a formidable list of questions, but I only have one for her, on amendment 5. It seems to me that the process we are describing does not enable people to discover who the user of an instrument was; it locates or identifies only the instrument from which the communication was made. Therefore, amendment 5 would be inoperative, because it could never be demonstrated that it was being used to establish who the user was as it cannot be guaranteed to do that.
