Youssri -- who filed the case in January -- represents 110 Egyptian and Western activists. The State Council opened the case on 6 April and has held three sessions since. In the first, the state's representative argued that the decision to construct a border wall with Gaza is a national security issue. Youssri countered this Tuesday by arguing that the wall is more a state intelligence issue than one of national security. There's a difference between stopping [underground tunnel] smuggling and thieves and protecting Egypt's domestic security from a national security viewpoint and within the standards set by international law. There are approximately 190 countries in the world and they don't build walls to protect their borders because they have border police, he added. The few border walls that were indeed constructed proved to be a failure and did not stop smuggling.
