My hon. Friend has expressed his views on a number of occasions on the need for continued focus on the balance between individual freedoms and collective freedom, because that collective freedom relies on our being able to conduct our affairs and to live our lives free from those who would do us harm. Sometimes people have sought to describe them as if they were in parallel, but I see them as mutually reinforcing; security and liberty must go hand in hand to develop and defend the fundamental principles that we have as a society, so to frame it separately misses the point.
My hon. Friend raises the important issue of how technology is evolving; it is constantly changing. That is why we see the import of the review by David Anderson, the independent reviewer of counter-terrorism legislation, to look at the issues more broadly, and at existing legislation and capabilities. We will come on to that, I am sure, in some of the subsequent debates in this Committee where that might be teased out in further detail, but my hon. Friend makes an important point.
