violence is not the answere

One day in Brazil , my friend and I were goin to the little cart at the other street to buy coconut water . After we bought the water a man came up to my friend and stole his money. My friend was fighting back while I was just looking. Then I turned around to throw the coconut away and i heard a gun shot. I looked. My friend was on the floor dead. I ran because I was so scared. I went home and called the cops. I started to cry because I felt guiltythat I did not help my friend. I lost a friend forever violence is never the answere
