THE incident of an American security official pointing a gun at a local police official as he was passing by the US Embassy in Islamabad with his family is highly offensive to the dignity of the country. The SHO has also alleged that the security man, who holds a diplomatic status, used abusive and humiliating language against Pakistan. Washington must realise that the fault lies with the arrogance of power that certain senior US officials at times show to register their country's global dominant status, little appreciating that it might filter down to the junior level and could be seriously mishandled. Understandably, the disgraceful behaviour has provoked countrywide adverse reaction and the Foreign Office has felt compelled to take notice. Its spokesman has been quoted as saying that the diplomat could be deported after declaring him as persona non grata. There should be no second thoughts and the concerned person should be expelled from the country without further delay.
