UK riots: Having learned nothing from Arab Spring, Cameron pursues a social media crackdown

"Everyone watching these horrific actions will be struck by how they were organized via social media. Free flow of information can be used for good. But it can also be used for ill. And when people are using social media for violence we need to stop them. So we are working with the police, the intelligence services and industry to look at whether it would be right to stop people communicating via these Web sites and services when we know they are plotting violence, disorder and criminality."

Prime Minister David Cameron of Britain addressing Parliament during a special debate on the UK riots.

As others have noted online today, the difference between "rioter," "protester," and "dissident" is not much indeed when those in power start down this road.
