I thank the noble Lords, Lord Davies of Gower and Lord Cameron of Lochiel, and the noble and learned Lord, Lord Keen of Elie, for tabling Amendments 51 and 52. These amendments are proposed and supported by three Members of your Lordships’ House who, between them, have considerable experience in what might loosely be called the law and order space. They are, in rugby terms, a formidable front row and, as such, I have considered what they proposed with care.

I reassure the noble Lords, Lord Cameron and Lord Blencathra, and indeed your Lordships’ House, that this Government are definitely against gangs and absolutely against graffiti. That said, we do not believe that these proposals are needed, primarily because the activities criminalised in these measures are already covered by existing legislation.

The intended effect of Amendment 51 is to criminalise the kind of graffiti which gangs use to mark what they feel is their territory and/or to threaten rival groups with violence. As the noble Baroness, Lady Doocey, said, this criminal behaviour is already covered by the existing offence contained within Section 1 of the Criminal Damage Act 1971. Section 1 is broad enough to cover graffiti because case law establishes that the damage does not have to be permanent, and it catches behaviour such as using water-soluble paint on a pavement or smearing mud on the walls of a police cell. In addition, Section 1 of the Criminal Damage Act has a higher maximum penalty than the proposed new offence, being punishable in the Crown Court by a maximum sentence of 10 years’ imprisonment.

Not only is the proposed offence not needed, there are very real problems with the structure of what is proposed; I will mention three, but there are others. First, this amendment creates an offence of strict liability. That means that the prosecution is not required to prove intention, recklessness or even knowledge. The result is a criminal offence which could be committed by accident. The criminal law does not like strict liability offences, and they are very rare in our jurisprudence. The reason is simple: we do not usually criminalise people who are not even aware that they were doing anything wrong.

Secondly, whatever the intention behind the drafting of this proposed criminal offence, in the way it is drafted, the definition of “gang” is so broad that it would capture both the Brownies and the Church of England, as well as football teams, drama societies and many other groups not normally regarded as criminal. I do not think that the noble Lords intend that a Christian cross chalked on a fence could potentially be prosecuted as a criminal offence.
