### Comment:
Whoever is spreading that as a company line needs to find a better one. Have you ever climbed a fence? What makes a DMZ wall or the berlin wall so effective wasn’t the wall it was there willingness to shoot anyone near it or trying to pass it? Are you will to shoot people trying to cross?

### REPLY:
Was every one who crossed the Berlin Wall shot? Or were some impeded just enough to be captured and returned? Regardless your own comment proves that having a wall provided guards with the ability to gain line of sight of people and were effectively able to respond.
