I sometimes think, I should leave this city..!

When my father was alive, he used to watch news channels only. It made my mind towards current affairs of the world and I also started watching some shows that were source of very useful information. But the things started to change and this change was sudden. News of killings, kidnappings, street crimes in Karachi were the headlines then. And as you all know Pakistani media very well, they keep showing such footages and clips again and again until they get a new one. Now I am a student and I have to travel 20-25 kilometers daily to go to my university. I mean I am exposed to the roads and places of the city on the daily basis. Now if around 10 people are killed on daily basis in different parts of the city and there is no one to take responsibility and provide security to the residents of this city, how can I feel freedom? how can i live here if I am not sure that I will come back to home in the evening or not? How can i adjust if my movements are controlled by the situation of the city. Which change daily and in seconds. Surety of life has been decreased a lot in the past few years here in Karachi. Even if the condition are okay... the street crimes and snatching of property at the center of road is so common that people avoid to go out foe enjoyment in the evenings.... So am i wrong if I think of leaving this city...?
