It would be somewhat ironic after reckoning GA supplied SF with dodgy info that JC himself would be the recipient of the same.
It just shows the risks of trusting too heavily the claims of prosecutors who haven't filed the said evidence in Court yet. We've just seen this issue blow up in the Morphew case where the prosecutor was making all kinds of statements off the record to 'journalists' off the record.
I am not so naive to realise that this doesn't go on a lot, and it is not necessarily a bad thing as then journalists know what angles to work, but it is strange, if then you go and assert those things as true on the record.
For instance in Delhi, it seems a lot of media knew about a critical piece of evidence in the case, but this was never put in the media, until the arrest dropped and the prosecutor stated its existence.
