Guido gives you a fair and balanced (as always) run down of everything you need to know on the developments of the last few days. As well as the key questions to both the Guardian and the security services that have gone unanswered.

• David Miranda, the partner of Glenn Greenwald, was detained at Heathrow by UK security services. They took his computer and memory card.
• It has since emerged that Miranda was carrying sensitive information from one of Greenwald’s contacts, something which was not mentioned in the initial Guardian report.
• Miranda says he did not know anything about the contents of the documents but was simply transporting them for Greenwald.
• Why did the Guardian fail to mention any of this in their initial report? Why has their side of the story, at least in part, begun to unravel?
• What justification do the security services have for detaining him under the Terrorism Act? Did they believe he was a terrorist?

• Alan Rusbridger claims that GCHQ spooks smashed hard drives in the Guardian basement after a series of demands that they were returned.
• Why did Rusbridger allow this to take place? Why did he not begin a legal battle or do his reporting from abroad, as he ponders in his article?
• With the knowledge that the Guardian would have made copies, for what purpose did GCHQ do this other than intimidation? What did it achieve?

Worthwhile further reading on this from Dan Hodges and David Allen Green. Both sides have important questions to answer…
