Since the article specifically talked about a Danish citizen helping non-Danish refugees, I am not sure where you came up with the differentiation comment.
And someone who is trying to enter or travel through a country illegal should be highlighted. If they are doing the traveling illegally, there might be a nefarious point to what they are doing.
If you are discussing different Danish citizens being highlighted, than your point would be spot on, but the article was not about that.
The article refers to Danish Citizens helping immigrants. That’s why those born outside Denmark yet Danish citizens are primarily and randomly contacted.
Denmark does not have an ‘immigrant smuggling’ problem now.
Will illegal entry be a problem for any country? Yes, it will, and has for many years.
The article is old news.
