Being one of the core values of the European Union, human rights have been centrally located in the European Union-Turkey relations especially since the country gained the candidate status in 1999. In human rights practices, the actor who comes to the forefront most on behalf of the state against the citizens whose rights must be protected is the police force. Therefore, the security practices enforced by the police form a huge part of human rights practices in the state and thus play a decisive role in Turkey's relations with the Union. This article presents an evaluation of the so-called 'internal security package', which has just passed into law, and its potential impact on European Union-Turkey relations. The package includes specific amendments regarding the police duties and authorities, which unarguably affect human rights practices in the country. As the Union lacks a uniform norm relating to the security practices the package in question contains, the answer to the question will be sought by screening two sources: EU progress reports on Turkey and relevant ECtHR decisions, which provide definite judgements regarding the threats and risks posed by the package under discussion.
