The noble Baroness raises the issue that the previous noble Lord also raised. It is extremely difficult, by the very nature of the activity, to police it 100%. In his Anti-Social Behaviour Action Plan, the Prime Minister made it clear that councils should take a tougher approach to enforcement and make greater use of the fixed penalties available to them. We have also taken steps to encourage councils to issue more of these penalties by increasing transparency on their use, through the publication of annual enforcement league tables. Councils must also now invest the income from this in enforcement activity and clean-up.
