I come from Poland, where the streets are generally quite peaceful. Some of my friends from France and Germany say things feel less peaceful there. They believe immigration has played a role in that. I’m not here to agree or disagree — I can only share my own experiences.
The more disruption there is in society, the more people seem willing to accept increased control by authorities. I'm not necessarily saying this is part of some grand plan, but it does seem convenient for politicians when circumstances justify stronger control measures.
