It appears this study shows that the majority of suspects for crimes are immigrants, which is an important distinction. I have no knowledge about the situation in Sweden, but in Germany there are known statistical problems like immigrants both having a higher chance of becoming suspects ("Tatverdachteffekt") and crimes where an immigrant is suspected are more likely to be reported ("Anzeigeeffekt").

Stastistics about suspects are most commonly used in studies like these because the police, due to the seperation of powers, usually has no or at least less statistics of the actual results of charges.

I would bet basically anything that inferring "did commit" from "is suspect" works very well in aggregate.

"Recent figures show that only 15 percent of all crimes are solved." https://sverigesradio.se/artikel/5399870

That low resolution rate alone introduces a margin of error that is larger than the difference between immigrant and non-immigrant suspects. It is therefore possible that the much higher immigrant suspect rate is entirely a result of biases.

This doesn't work numerically if each crime averages more than one suspect.

This is a good point! I wonder how often that's the case...

Yes, exactly kind of my point.

I’m not suggesting however that because they are immigrants they commit more crime. Note most violence is committed by 2nd generation immigrants - so they’ve been born here. How’s that for a failure of society...

They are simply people on the outside living surrounded by people leading lives they cannot relate to.

We’ve made it terribly difficult to attain this norm life as well making it even more unrelatable.

One thing that's great for societal stability is not too much inequality of wealth. Another thing is cultural homogeneity. We're probably seeing both at play in Sweden.

Young men shooting at each other in the street sure is a culture clash. This culture need to be canceled!
