• Norwegian, Finnish and Polish border forces seem to disagree with your estimate on border fences and seem to think as them as valuable tools in addition to others they have. Those are the ones who have had to deal with this migrant issue.

    • Is it the people actually studying effectiveness of preventing security threats from crossing borders, or the politicians and leaders who want to be seen as doing something visible to deal with the ‘migrant issue’ dispite the pure absurdity of suggesting that people who crossed continents will see a fence and just decide to stay illegally in Russia of all places?

      • In Finland it was the border guards who were calling for this. Same for Poland. And it’s easy to see why since it can play an important part in controlling but also as a deterrent and help in knowing about illegal border crossing.
