Women's racist rant on a London train goes viral... and now she's been arrested.

Here's the report of her arrest. Here's the clip, posted 2 days ago, with almost 7,000 comments.

Here's the Metafilter discussion, where one commenter says "I'm ambivalent about this in that there is a part of me that doesn't want to feel any sympathy for her at all... [b]ut there's a tinge of pitchforkery (jumped on by the usually deeply racist media) that gives me huge pause for thought" and links to this aggregration of Tweets:

[O]n Twitter, the righteous have massed. The Twitter Hunters are in favour of shooting the mother and leaving her child possibly orphaned. Some order a hit. Others want her to be sent to Africa where intolerant blacks will judge her. Others want “the slag” raped. Intolerance will not be tolerated.
