UK Prime Minister David has actually said it and ordered it be done:
“Everyone watching these horrific actions [rioting and looting] 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.”
In an emergency session of Parliament today, Cameron announced that officials were working with the intelligence services and police to look at how and whether to “stop people communicating via these Web sites and services when we know they are plotting violence, disorder and criminality.”
Our moral authority to demand openness in other society erodes.
