Headley's testimony was the 'prime evidence' so far.
Dont see how this has changed
Without it there is nothing to support ISI involvement, not even rogue agent invovlement.
In fact, even the allegation of 'rogue agents' needs to be established through verifying the identities of the 'ISI agents' allegedly invovled', or at least verifying that they were indeed 'ISI agents'.
As of now, Headley's credibility has not been dismissed....
And the ISI is not on trial...Its Rana....
Headley has stated that his handler was a Major Iqbal...who is an ISI agent along with a few others....So the identity or existance of these "rogue" agents will not be the point of this trial....
So far Headley's credibility seems to be doing just fine considering that the US considers him their star witness
Lots of egg on the faces of the Indian media and others (Western news organizations and analysts included) that were trumpeting the so called 'Headley Confessions' to Indian investigators.
Yet to be seen....Seems Pakistanis believe in premature celebrations...
Indian interest should be served with the mention of ISI whose elements were involved in acts of terrorism.....as long as this comes out as a by product of this trial, even based on Headley's testimony (proven or not) should suffice
