Introduction

Urban jihadism has claimed 597 fatalities and thousands of injured in the territory of the European Union since 2004 and the recruitment of foreign jihadist fighters has reached estimated figures of between 25,000 and 35,000 men and women, of whom 20% were European citizens. Global terrorist organizations that recruit urban jihadists and foreign fighters to carry out various acts of terrorism have a radical and violent religious ideology, which rejects the socio-political organization systems of Western countries, as well as the traditional cultures and structures from many Muslim countries. The fight against terrorism and radicalization inevitably involves rethinking the balance between freedom and security, which essentially affects the principle of the rule of law. Judge Ruíz Yamuza is convinced that this type of measure can be a more useful alternative to prevent the radicalization of other individuals and the reintegration of those convicted of crimes of jihadist terrorism.
