I don't disagree with your racial implications of shithole countries, over time, but if you're talking about bringing in an immigrant or 1000 right now, you can look at the immediate environment and make a judgement call on that alone. Shithole countries drag everyone down to the low-IQ mean. Drop an intelligent Englishman into that society as a baby and he'll either end up dead or the most successful thug in the village. You don't want to import that any more than a Shithole native or a leftist.
This changes if you're importing orphan refugees. Then you'll want to look at race directly. I don't know anything about the attacker or when he got imported though.
