Sennels wrote an article about his findings in New English Review:
NEW ENGLISH REVIEW--February 27th 2008. On a cold and windy Wednesday (for cyclists like myself), I took a deep breath, grabbed the microphone and did something that changed my life. In front of the Copenhagen Mayor’s Integration and Social Services Office there were gathered several journalists, a faithful Muslim musician from the famous MTV-band ‘Outlandish,’ dozens of Imams and Muslim spokesmen and a couple of hundred social workers with Muslim and Danish backgrounds. I began to say what everybody already knew, but, what nobody either wanted or dared to say: that those who are referred to as foreign criminals, religious extremists, or terrorists in the making and who are the cause of lawless parallel societies (what the conference "Diversity and Safety in the City" was about) are all Muslim. I argued that we should stop talking about "criminal foreigners" and start using the more precise term, "criminal Muslims." As a psychologist, having had more than a hundred Muslim clients, I told them that politicians and professional social workers need to understand the cultural and religious backgrounds of criminal foreigners. That is, if we want to come up with, at least, somewhat effective and targeted plans on how to reduce the social unrest, anti-democratic religious movements, the violent and anti-social forces among foreigners.
I was met with strong criticism from all sides and no support at all!
Just as most soldiers in the front lines die in the first attack, many of those who attacked political correctness have experienced negative professional or social consequences. I was no exception. The Mayor of Social Services was clear. I should either refrain from using stigmatizing expressions or find myself another job. Actually I was trying to stop the so-called stigmatization of all the non-Muslim immigrants by focusing on the one group that creates all the problems. But you can't fight City Hall. Our biggest national newspapers and radio news programs got hold of the story and the mayor was strongly criticized by the media experts on free speech and by the Danish blog-sphere. For about a month there was not a day when my name was not in one or more newspapers and the fighters for free speech took another round. I was no longer an anonymous psychologist. My name was known by everybody who read newspapers in Denmark and especially Islam-critical blogs on the internet put me in the spotlight.
Instead of keeping my mouth shut, I decided to write a book about my experiences with Muslims based on hundreds of therapy sessions. The whole circus that had happened concerning my case had already shown the necessity of breaking the taboos around criminal Muslims. Further, a serious discussion about the relationship between the Muslim culture and criminal, antisocial behavior is, indeed, very much needed. I managed to negotiate a deal that gave me four months severance pay. I am probably the first psychologist in Copenhagen who was offered $20,000 dollars for quitting his job voluntarily. I guess they just wanted to get rid of me, ASAP. I found a well-paying job as a Military psychologist doing psychological screening of soldiers returning from the war in Afghanistan. I also started writing my book, in which I describe a psychological profile of the Muslim culture. The title of the book is Among Criminal Muslims: A Psychologist's Experiences from the Copenhagen Municipality. (Free Press Society, 2009).
After having consulted with 150 young Muslim clients in therapy and 100 Danish clients (who, on average, shared the same age and social background as their Muslim inmates), my findings were that the Muslims’ cultural and religious experiences played a central role in their psychological development and criminal behavior. "Criminal foreigners" is not just a generalizing and imprecise term. It is unfair to non-Muslim foreigners and generally misleading.
Discussing psychological characteristics of the Muslim culture is important. Denmark has foreigners from all over the world and according to official statistics from Danmarks Statistik all non-Muslim groups of immigrants are less criminal than the ethnic Danes. Even after adjusting, according to educational and economic levels, all Muslim groups are more criminal than any other ethnic group. Seven out of 10, in the youth prison where I worked, were Muslim.
