Well there's 2 major differences here: Firstly, the sheer volume of input that comes into Google video every day. You can't reasonably be expected to pre-vet all that. TV programme makers and newspaper article writers/editors are working on one thing at a time, and have time to check out what their contributors are saying.
Secondly, the ease of correction. In the newspapers, you can't exactly go out and recall every copy of that issue and replace it with an updated one. On TV, you control the distribution, and people will be watching at one specific time or have to wait for the repeats, which again you can hold off until it's corrected, but everyone will still see the same thing, ie the racism. With google video, you have no guarantee that everyone saw the video at the same time, with the same content, and by taking it down you prevent a lot more people from seeing it, whereas on TV they'd have seen it if they were going to; you've already done maximum damage.
Don't ask me where stuff like BBC iPlayer fits into this.
And no, I don't have a picture of my coat. It's an ancient Burberry one, with a bit of added trimming around the sleeves and the bottom.
