Terrorism Prevention and Investigation Measures Bill

Would the noble Lord like to say anything about the development of technology? He may be overlooking the fact that individuals who are subject to these measures will almost undoubtedly be tagged. I do not know much about it, but I am sure that the technology is developing as we speak, and that it is possible to know where people who are tagged are going, and whether they are going where they should not be going. Surely that needs to be taken into account.
