1. Within the framework of Decision No 276/1999/EC of the European Parliament and of the Council and in order to intensify measures to prevent and combat the production, processing, possession and distribution of child pornography material and to promote the effective investigation and prosecution of offences in this area, Member States shall take the necessary measures to encourage Internet users to inform law enforcement authorities, either directly or indirectly, on suspected distribution of child pornography material on the Internet, if they come across such material. Internet users shall be made aware of ways to make contact with law enforcement authorities or entities which have privileged links with law enforcement authorities, to enable such authorities to fulfil their task of preventing and combating child pornography on the Internet.
2. Where necessary, and taking account of the administrative structure of each Member State, measures for the promotion of effective investigation and prosecution of offences in this area may be the setting-up of specialised units within law enforcement authorities with the necessary expertise and resources to be able to deal swiftly with information on suspected production, processing, distribution and possession of child pornography.
3. Member States shall ensure that the law enforcement authorities act swiftly when they have received information on suspected production, processing, possession and distribution of child pornography material. Law enforcement authorities may defer taking action if and as long as tactically necessary, for instance with a view to getting at those behind the criminal operations, or at networks (child pornography rings).
