just cos someone says it's so, and it sounds plausible, doesn't validate it.
for example: dozens of al qaeda have snuck into the US in container ships, prepared to attack US targets. true or false? according to sourcesŪ, it's true.

they also claimed in May that OBL was in Kashmir. plausible, but unverifiable. and not "credible" by any means.
these same sourcesŪ claimed back in November that Russia was invading Afghanistan from the north with 100s of thousands of troops. dont recall hearing any more bout that one.
i think that i shall come out with a press release stating that OBL was injured at tora bora, and subsequently died of his injuries. i will back this up with the fact that nobody has seen or heard of him since then. no tv, nothing. for a man that obsessed with CNN and Al Jazeera, that's proof enough for me, the hack journalist. i'll add in a few uncorroborated reports of tall guys being seen in coffins, and that should be good enough.
