The right hon. Gentleman makes an important point, but that is the same as any other decision that the police make. We have an independent police who make independent decisions based on their best knowledge at the time. To say that no policeman is ever influenced by events going on is wrong. Of course they are. They can listen to arguments, but it is their decision. We looked carefully at that to ensure that the police have and can keep powers to make the decision as to what is a riot and what is not. There is a whole debate to be had about that, but the definition in the Bill is important in allowing the police to continue to have the powers that they have had. That is why I support the clause.
