In the wake of the riots in UK, Prime Minister David Cameron during his address to the Parliament said "Some people have raised the issue of the Army. The Acting Commissioner of the Metropolitan Police said to me that he would rather be the last man left in Scotland Yard with all his management team out on the streets before he asked for the army. A lesson for our leaders asking for Army's help all the time for the issues which do not fall under their line of duty. DR. IRFAN ZAFAR, Islamabad, August 16.
