Sir: The rising trend of killing in Pakistan is alarming. People are killing each other without fear. There have always been people in our society who take the law into their hands because they do not trust the legal system of the country, but now most of the people resort to killing on suspicion, in the name of honour, and even on petty squabbles. It is unsettling for the country to witness violence becoming a normal way of settling differences or teaching others a lesson. It is the responsibility of government to look into this serious matter and do something about it.FAUZIA MANSOORLahore
