"This violence by Muslims is usually labelled simply as "crime," but I believe it should more accurately be called Jihad. Those who know early Islamic history, as described in books such as The Truth About Muhammad by Robert Spencer, know that looting and stealing the property of non-Muslims has been part and parcel of Jihad from the very beginning. In fact, so much of the behavior of Muhammad himself and the early Muslims could be deemed criminal that it is difficult to know exactly where crime ends and Jihad begins. In the city of Oslo, for instance, it is documented that some of the criminal Muslim gangs also have close ties to radical religious groups at home and abroad. As Dutch Arabist Hans Jansen points out, the Koran is seen by some Muslims as a God-given "hunting licence," granting them the right to assault and even murder non-Muslims. It is hardly accidental that while Muslims make up about 10% of the population in France, they make up an estimated 70% of French prison inmates.
In the city of Antwerp, Belgium, Marij Uijt den Bogaard from 2003 to 2006 worked as a civil servant in the immigrant borough of Berchem. She noted how radical Islamist groups began to take over the immigrant neighbourhoods, but was fired when she warned against this danger in her reports to the authorities:
"Many victims of burglaries in houses and cars, of steaming and other forms of violence, can testify that aggression by Muslims is not directed against brothers and sisters, but against whoever is a kafir, a non-believer. Young Muslims justify their behaviour towards women who do not wear the headscarf, whether Muslim or non-Muslim, by referring to the Salafist teaching which says that these women are whores and should be treated as such. They told me this. I wrote it down in my reports, but the authorities refuse to hear it.""
