Europe should likely overhaul immigration to allow very easy inflow from countries whose prior immigrants show low crime rates and nearly ban inflow from high-crime ones.

I think we should use this kinds of data to completely turn around Europe's immigration policy: - We should have super easy inflow for immigrants from countries whose previous immigrants have shown low crime rates You're from Japan? Just fly here and you can stay forever - We should then almost completely ban any inflow from countries whose previous immigrants have shown high crime rates with instant deportations
