The issue is almost always culture and class

From Europe Shows a Clear Link Between Immigration and Crime -- Like the One the U.S. Seriously Downplays by John R. Lott Jr. & James Varney.  Pertinent to addressing the logic and evidentiary failings of the Critical Race Theorist who wish to project a model of race relations which does not actually map to the real world.  

The issue is almost always culture and class rather than race per se.  

The article has an agenda but is none-the-less packed with useful information.  

Until recently, Sweden’s Crime Prevention Agency had not offered a comprehensive look at the issue since 2005. In October, however, the agency acknowledged that Sweden ranks “very high” in homicides when compared with other European nations, with a murder rate of 4 per million as opposed to the continent’s 1.6 per million.  

In 2020, Swedish sociology professor Göran Adamson published a crime study showing an unmistakable link to immigration. It concluded that from 2002 to 2017, 58% of criminal suspects in Sweden were immigrants. That figure rose for murder, attempted murder, and manslaughter, where immigrants were identified as suspects in 73% of the cases, and robberies, in which immigrants were suspects in 70% of the cases. 

Adamson told RCI that while members of some immigrant groups, such as Vietnamese, were less prone to commit crimes compared with native Swedes, others such as those from the Middle East and Africa – regions that account for most of the immigration to Sweden – were much more likely to do so. Overall, Adamson’s study concluded that Sweden’s murder rate had quadrupled due to immigration. Consequently, he said, he found RCI's statistical analysis to be “believable.” 

Researchers in Denmark reached similar conclusions about immigration and crime. An index shows that crime in 2020 was 51% higher among male immigrants and 149% higher among male offspring with a non-Western background than among the entire male population.  

The point is not that immigration is bad but that immigration has consequences.  I would go beyond Lott and Varney and derive a different conclusion.  Open societies can absorb up to 15% of their population as immigrants but you have to be careful if you start exceeding that level.  Second, eliminating illegal immigration is critical.  The more you are able to select non-randomly and select for culture fit and class compatibility, the more immigrants you can accommodate.  The more illegal immigration there is, and the more that it is constituted of individuals with poor culture and class compatibility, the more financial, criminal, and cultural difficulties you will experience.

Finally, immigration policies which lead to bad economic, financial, cultural and criminal consequences impose virtually all those costs on the bottom quintile of that native population.
