[Prophet in the wilderness]

Why are they ( CIA ) telling us this information ?
Just like a high profile intense investigation, you keep your mouth shut, and keep a clamp down on any information getting out.
That would be the last thing I would want to do , is to let the enemies of the USA and OSBL know that we know were he is.
I would let him keep guessing, unless this is some kind of SYOPS to psych him out.

unless this is some kind of SYOPS to psych him out

It is partially that - However, there is nothing more complex than avoiding the obvious - and the fact is UBL doesn't have many better options then what he currently has - therefore we are giving him nothing by our CIA director saying what he said above -

He is in the Pakistan border region - He is going to live there until we find him and kill him there - That is the bottom line and he knows it -
