Anonymity – Ambiguous.. why is everyone so coward!!

TOI reported today:
NEW YORK: Former Pakistani army officials trained the terrorists who went on rampage last week in Mumbai , The New York Times said on Wednesday quoting unnamed Pentagon officials.

I don’t understand why new papers even report the statements of people (officials) who don’t have the balls to stand by what they speak. After Mumbai Attacks, I have been reading and hearing from all corners, about pak-link of terrorists. There has been no *solid* evidence. Those who claim to have it, say that wouldn’t share it now. Many of those who allege pak-terrorists are anonymous officials, be it those babus in external affairs ministry, be it some diplomat, or the so called reports of CIA, no body comes out in open and speaks without fear. Strangest part is that most pak-link newspaper reports are reported by The Observer, The Guardian, and NYT. Where are the TOI’s and HT’s of India? In Indian print media, like the photos of events in India, which are almost always clicked by Agency, or Reuters or AFP, now even intelligence reports of terror attacks are also out sourced from foreign press!
