By banning the entry of cars registered in Russia, the European Commission aims to prevent sanctions evasion.
I had a completely different thing in mind: Russia is letting murders and rapists out of prisons, if they murder and rape a few months more in this war. So Russia has those people back out on the streets, as civilians, without the required rehabilitation measures or without serving their life sentence.
For the safety of their people, all countries should close their borders for Russians.
