Sir: Now that the CCTV footage of Muharram riots has been released and is being aired on every news channel, it is very easy to identify who is responsible for acts of arson in the aftermath of the attack. It was also surprising to see that the police and rangers were present at the areas under attack, but not doing anything to stop these people who were destroying shops, banks, cars, etc. I appeal to the Chief Justice of Pakistan to take notice of this matter, as he seems to be the only man interested in solving the problems of the people.MUBASHIR MAHMOODKarachi
