The current study is based on my PhD thesis, which I defended on 9 June 2018. The seed for this project was, however, already planted in 2006 when I first got interested in the work of the International Criminal Police Organisation (Interpol). Through the years, I have met countless people who have given me their time and knowledge and assisted me in understanding the details of the problems I was researching. People have pushed me and cheered me when the project seemed too much to handle, and assisted me in moving forward by providing opportunities and introducing me to new contacts. I wish to especially thank Professor Christopher L. Blakesley and Dr Saskia Hufnagel for their invaluable help in finalising this project. They have both been incredibly flexible and supporting. I could have not wished for better guidance! Thank you, Professor Jukka Kekkonen, for acting as my thesis supervisor and general supporter and for enabling amazing opportunities. I also wish to thank my personal mentors in the field of research, Professor Philip Stenning and Dr Tuija Hietaniemi. I have learned so much from you both. In addition, an important thanks goes to the Emil Aaltonen Foundation, the Finnish Cultural Foundation and the Kone Foundation, all of which have enabled me to properly concentrate
