Twitter and YouTube users’ disgust has drawn swift attention to the appalling racist behaviour of a woman on a Croydon tram today. In a video called My Tram Experience a woman with her son on her lap is shown swearing and insulting fellow passengers. She shouts at them: ‘My Britain is f— all now,’ and ‘Go back to Nicaragua, or wherever you come from.’

Social media helped the matter to come to the attention of police who arrested the woman today.

This is just the latest in a swathe of videos to have appeared on the Internet demanding justice, often for the actions of over aggressive police such as the incident in London, Canada where a man was tasered in the face by a Police Officer. Or more recently the infamous Occupy California University pepper-spray police incident.

Whilst there is a danger of vigilante action (the California pepper spray cop had his home address briefly posted on the net) the web is proving a powerful tool for justice. The Net also helps as a kind of social therapy in mocking wrongdoers. Creating Photoshop mock-ups of the CU police officer in his scarily relaxed pose spraying anything but Occupy protesters has become a trend on one site.

I wouldn’t be surprised if spoof videos of this bitter woman appear by tomorrow. A dance remix of her racist tirade to take the sting out of her words perhaps?
