There really needs to be a Mafia like community to keep these savages on check.
Like the Italians did when they migrated in the mid 20th century before the next generation become fully settled in the West and behaved like a human being.
One thing I never get is that some of them were warlords, soldiers or criminals who did shady shit at home before the 90s so they had the experience to become community leaders and instill fear.
Instead, they did nothing and let the next generation savages roam around freely and give everyone a bad image.
