I remember when I was in Karachi and my friend asked me to come over. It was alarming for me that no one stopped me at the entry point. The Karachi University (KU) has many entry points which are a potential security risk. Some people go across KU who literally have nothing to do with it. At a time when the commercial capital faces turmoil, it is important to have tight security measures. The troublemakers cannot be stopped overnight but with concrete steps, the security situation can be certainly improved. ALI HAMDANI, January 8.
