Vulnerable mobile phone!

A very informative article on the tracing of Osama bin Laden by the CIA, was published in a local English daily recently. Till date, it was the most logical and realistic background about the secret US mission to neutralise bin Laden at Abbottabad in Pakistan. One can understand the US logic to carry out the mission on the sly; without informing Pakistan, their close ally! ISI had identified the same mobile phone talking in Arabic earlier from Nowshera, then Peshawar and finally from Abbottabad, and duly informed the CIA; for necessary follow up. Quite logically, and may be mistakenly, the CIA assumed that the Abbottabad message's source was investigated by the ISI; but kept secret from them! This led the US to plan and carry out through surveillance and ground investigation independently and reach the conclusion that "some high-value target lived in Abbottabad"; which later events proved to be a fact.
