Public Disorder: Policing

My Lords, I know that it is 30 years since I was last involved in riot control and that the Falls Road is not the same place as Parliament Square but, to amplify the question asked by the noble Lord, Lord Dubs, a word has crept into the vocabulary about what is going on in policing. It is ““kettling””. Can the Leader of the House explain what it means? I hope that it does not mean trying to contain a crowd in a space because, in my experience, one of the things that a crowd always needs to know is where it can go to, as do the people controlling the crowd who need to try to encourage them to go there.
