While i do not want to defend the position of anovikov, i have to note there is a big difference in border protection against entering a country and leaving a country. This is e.g. explicitly stated in UDHR, which recongizes a human right to leave any country, and only right to enter a country of citizenship. The border situation with communist countries was significant not only it proves intent of these countries to shoot on those trying to cross borders, but mainly it proves that situation there was so bad that people trying to leave even if that means risking death in border crossing.
