Do you have any evidence that immigrants are more likely to commit crimes than demographically similar natives? At all? Or would you just like to use a victim as a bludgeon against those you hate?
To give a quick example from my country: in 2016, in 20 percent of all sexual crimes the suspect was a foreigner; if you count only the cases where the police has a suspect then the number rises to 29 percent. In 2015 the proportion of foreign suspects had been around 10 percent; in the autumn of that year Finland experienced the largest influx of asylum seekers ever.
And this is only counting foreign citizens, not Finnish citizens with a foreign background (as the government does not keep statistics on ethnicity). The number of foreign citizens in Finland is no more than a few percent of the population.
