Sir: On April 12, a thief when rounded up by police threw acid on the policemen to avoid arrest. This is an eye-opening incident as it shows that acid has increasingly become a tool to show resentment, take revenge, and now even attack the police. I would say it is the lame attitude of the government that is letting such horrific incidents take place in the first place. By legislating, one cannot do away with the tendency in society to use acid as a lethal tool. Unless government regulates and restricts the sale of acid and enforces strict policies, this monster will keep raring its head. SADAF KHOT Karachi
