Big brother is ‘watching’

Having remained silent on the memogate scandal for the last few months, the United States finally released a statement demanding a fair and transparent judicial process.
US senators have reportedly voiced concern over former ambassador Husain Haqqani’s ‘mistreatment’ in Pakistan. Meanwhile, the State Department’s spokesperson also told journalists in Washington DC that the US believes “it is important for us to speak out, as we do around the world, about an appropriate constitutional and legal process for him and to make clear that we’re watching.”
What effect, if any, will this and similar statements have on the judicial process?
Given the earlier silence, do these statements mean the US is concerned about the judicial process?
