Determine what makes a file classified.

Should all classified files remain so?

Do you trust the government to act honestly and within the law? If they are in breach of the law, do you expect them to declassify files identifying such breaches?

Does is it therefore matter who exposed said breach or how they obtained the information?

Or is this all a case of the government sympathisers living life by the adage of 'ignorance is bliss'?

How about, oh wizened sage of the seas, you actually explain your little rant in detail?

Sounds increasingly like Mr Miranda has acted as a mule for his journalistic partner or this Laura Poitras and carried stolen classified material (unwittingly or not - if willingly he's lied to airport security) and has spat his dummy now he's been found out. You can see the bottom lip when he's snapped arriving at Rio.

Don't want to be picked out for detention and questioning? Don't get involved in the first place. Choose to get involved and don't spit your dummy when you're 'picked on'.

The poor cherub was detained for a whole nine hours. Oh the trauma. I'd be more impressed if they bumped him off by shining a light at his limo as he raced through a Paris tunnel.

Its not scientific but Skyscanner shows no direct flights from Berlin to Rio, so he would have needed to change. He would have remained airside though so not technically in the UK. Who detained him? Do the Met have jurisdiction airside?

There are flights to Rio from Amsterdam and Paris.

The cheapest and most frequent flights are BA through London. But why in hell would someone deeply involved in the Snowden case, and indeed carrying classified files received from him, travel through London when it's just as easy to go through Paris? To me they were either completely stupid to go through London, or they did it deliberately because they knew he'd be detained and they wanted the scandal.

I've no idea about the jurisdiction issues.

Indeed, though he could easily connect through JFK (bad idea), Heathrow, Amsterdam, Paris, Frankfurt or Madrid onto direct flights. Perhaps the fact the Guardian paid for his flights limited his options?

I don't work for the Guardian either, and I'm not a journalist. But I quite fancy a trip to Rio, so I was wondering if the Guardian would pay for my air fares too?

Paragraph 2(1) of Schedule 7 of the Act says:
An examining officer may question a person to whom this paragraph applies for the purpose of determining whether he appears to be a person falling within section 40(1)(b)

Section 40(1) says:
“terrorist” means a person who …
(b) is or has been concerned in the commission, preparation or instigation of acts of terrorism.

But paragraph 2(4) gives a bit of wriggle-room to the police to determine (as per 2(1) whether or not the person being questioned appears to be a terrorist ... it says :
An examining officer may exercise his powers under this paragraph whether or not he has grounds for suspecting that a person falls within section 40(1)(b).

Bearing in mind that most people stopped for reasons of P2(4) are released within an hour rather than full nine hours allowed, this case does fall outside the norm ... and as Miranda was released without charge ... and as no-one, including the police, has said that there was any suspicion of him being a terrorist ... it does make the case newsworthy and does raise the issue of whether the law is being used/misused.

I know right!

They stamped it secret and everything, we don’t need to trouble ourselves with worrying about anything stamped secret. Only good things like surprise parties or presents from Santa are kept secret, Or Victoria’s secret, another good thing. Nobody ever did anything nefarious in secret and nobody ever tried to keep their mistakes and wrong doings secret. Especially politicians, the police and army. People in power have always, throughout human history been the most trustworthy ones.

He was stopped under Schedule 7, the act makes clear that police can only detain someone to assess whether they are: involved in the commission, preparation or instigation of terrorism. There's not a shred of evidence that Miranda falls under any of those three categories, therefore the stoppage was unlawful. Anything else is fluff and spin.

I have no doubt this will end badly for Cameron, May, The Met and the security services.

Mind you, I suppose Miranda should be thankful, the last Brazilian to fall foul of the Met was executed

Wrong.

The legislation states no suspicion is necessary.
