Sounds like racial profiling to me.
I spent a few weeks in Italy 20 years ago. Found the African sidewalk vendors rather scary, but not overtly so. Friend was just there last month, found Italy filthy and overrun with really scary Africans. She said it was more frightening than Egypt, which wasn’t especially scary. Just overrun with Egyptians.
Big population increases going on in the 3rd world. Huge problem for all of us.
