On Thursday last week, a US judge ruled that Twitter must release the details of Icelandic MP and former WikiLeaks volunteer Birgitta Jonsdottir's Twitter account and those of two other Twitter users linked to WikiLeaks.

Jonsdottir learned that in January of 2011, her Twitter account was being watched by the Justice Department because of her involvement last year with WikiLeaks' release of a view showing a US military helicopter shooting two Reuters reporters in Iraq. Jonsdottir believes the US authorities want to use her information to try and build a solid case against WikiLeaks founder Julian Assange.
Jonsdottir says:
This is a huge blow for everybody that uses social media. We have to have the same civil rights online as we have offline. Imagine if the US authorities wanted to do a house search at my home, go through my private papers. There would be a hell of a fight. It's absolutely unacceptable.
