My Lords, I am grateful to the noble Baroness, Lady Chakrabarti, for drawing attention to the points I made, and I am sorry if I sounded too aggressive on some of them. The point I did not make, which I shall make now, is on how much crime is committed. One would expect that, in most cases, it would not be the commission of crime so much as association with people while they committed crimes, with the person in question not necessarily being directly involved but having some complicity, which is one of the problems.
The requirements, as I understand them, if they are in that situation and a criminal conduct authorisation is issued, are that it has to be proportionate, it may not be issued if what is sought to be achieved can be done in another way, and it has to be part of an effort to prevent more serious criminality. Those three conditions are perhaps not mentioned very much but are important.
I have left out some issues that I might have discussed. We have just talked about possibly leaving the Department of Health and Social Care out of the Bill. Think of this moment when organised crime, throughout the world, is seeing how it can get into the vaccines business in one way or another. The challenge that that will pose will feature in our news broadcasts and papers in the days ahead. It will obviously be a big issue. One recalls that the NHS was practically brought to a grinding halt from its systems being hacked and disrupted.
There is this, as well, if it is not too dramatic. At the time of Brexit, when we may be moving towards no deal, there is an idea to take from HMRC its ability to keep every possible assistance. In trying to deal with some of the problems it will have, it will need all the help it can get.
My concern about these amendments, and referral to the police or judges to overview the operations of CCAs, is that a clear structure is set up. The Investigatory Powers Commissioner is a very senior judge and the judicial commissioners are very senior. My concern all the way along is that nobody has challenged how vital covert intelligence sources can be, in a range of different fields. The question is whether we can still keep those covert sources coming. The more we expand the range of people who have access to that information, the bigger the danger of leaks, and then there will be fewer sources available in the future. That is why I think the structure set up of the Investigatory Powers Commissioner and his judicial commissioners, with a tribunal and an annual report to Parliament on its operations, has important safeguards. Going much further than that starts to undermine the security of the information and imperil the safety of some brave people, who are giving evidence to help keep our country safe, in a range of different fields.
