My Lords, I say again that we do not know the origin of the attack. Noble Lords will know that the type of weapon used in the attack was an RPG 22 rocket-propelled grenade. That, regrettably, is a device used by many groups. For that reason the police, with great energy, are trying to discover who is responsible. I cannot concede what the noble Baroness says about an amendment to the Police (Northern Ireland) Bill. Appropriate steps have been taken and will continue to be taken to ensure that our nation remains secure.
