The Free Movement on Suspension?

The Free Movement of Persons, being one of the core principles in EU-law, has come under strain from economic and political difficulties within the EU.

This was accepted by the European Commission despite criticism. A few weeks later, Denmark, under pressure from their far right-wing Danish Peoples Party, (Dansk Folkeparti) reintroduced their border checks towards Germany and Sweden.

Regarding possible restrictions of using social media in order to quell riots; the Prime Minister of the United Kingdom, David Cameron, stated the following today:

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 websites and services when we know they are plotting violence, disorder and criminality.”
