Det har også vist sig at have en merværdi for vores Europæiske Union, at de europæiske institutioner, navnlig Kommissionen og Rådet, reagerede så hurtigt på terrorattentatet den 11. september ved at udarbejde en hel foranstaltningspakke, der rakte lige fra en definition af terrorisme over den europæiske arrestordre til organer som fælles efterforskningsteam hos Europol.
The added value of this European Union of ours was also shown by the speed with which the European institutions, in particular the Commission and the Council, responded to the terrorist attack on 11 September with a whole package of measures ranging from the definition of the common offence via the European arrest warrant, to facilities such as joint investigation teams in Europol.
