Its simple....even if you see some suspicious men...even if you confirm that they are outsiders and indulging in anti-national activities....JUST STOP AND FIRST CONFIRM.... which community do they belong to.....if its hindu chase and if necessary kill them....but if muslim then wait till they actually commit the crime(blasts etc)....learn to be secular.....for 60 years u guys are being taught...still ...u r just.....(I think our intelligence officers have learned this pretty well)
