I think Bawer is using some interpol figures from 2003 published in the Economist, which has later proven to be wrong.
Wikipedia states:
In 2003, there were 189 homicides in Sweden [3]. In 2001, there were 169, which gives a rate of cirka 2 murders per 100,000 inhabitants. This figure is in line with most European countries, which also have a level of between 1-2. For comparisments: U.S has 6 murders per 100,000; and Russia: 20.5.

"Even more news from Sweden's third largest city, Malmö, the evolving tragedy of failed immigration policies and runaway crime rates. Set to become the first major Scandinavian city with a Muslim majority a few years from now, it is the horror story in the ongoing collapse of Swedish society."
Wikipedia is the MTV of research.
Americans of a European ancestry have rates very similar to those of European countries.
