Duh.

Should a news organization knowingly air false or misleading footage?

Hummm, let me think about this... err umm, No?

How about a somewhat less hypothetical question?

Except that is the question that the video is trying to raise: if they shouldn't, but did, and in their view it was obviously staged, then what can be inferred from them airing it anyway?

Very nice with the link. You caught me trying to get you to address what the video is trying to say rather than what you want to talk about. Tricksy me.

Hoping this thread might yield a spectacular dance number, but reading the posts and realizing I was about to be suckered into another political thread, I will pass and paste a link of my own:
Bollywood gangster comedy makes Gandhi new pop icon

The "point" the video is trying to say is flawed in the same manor as your phrasing of the question. It's based on inconclusive arguments and blatant speculation.

Who made this video? Why did they make it?

At least with 60 Min. and other mainstream media, they don't hide who they are and what they are doing.
