What Bad, Shameful, Dirty Behavior is U.S. Judge Richard Posner Hiding?, por Glenn Greenwald:

Richard Posner has been a federal appellate judge for 34 years,(...). At a conference last week in Washington, Posner said the NSA should have the unlimited ability to collect whatever communications and other information it wants (...)

His rationale? “I think privacy is actually overvalued,” the distinguished jurist pronounced. Privacy, he explained, is something people crave in order to prevent others from learning about the shameful and filthy things they do (...)

Unlike you and your need to hide your bad and dirty acts, Judge Posner has no need for privacy – or so he claims: “If someone drained my cell phone, they would find a picture of my cat, some phone numbers, some email addresses, some email text,” he said. “What’s the big deal?” He added: “Other people must have really exciting stuff. Do they narrate their adulteries, or something like that?” (...)

[I]f Judge Posner really believes what he’s saying about privacy, and if it’s really true that he personally has nothing to hide – he just has some cat videos and some pictures of his grandkids – then he should prove that with his actions. Every day, he should publicly post online all of the emails he sends and receives, along with transcripts of his telephone and in-person conversations. Or just put a recording device in his office and on his person, and upload the full audio every day. He should also put video cameras in all the rooms in his home and office, and stream it live on the internet 24 hours a day. If there’s a specific reason for excluding a particular conversation – say, something relating to attorney/client privilege – he can post a log identifying the metadata of the withheld communications. (...)

What possible objections could he have to any of this? After all, the Hon. Richard Posner has nothing to hide. He’s a good person. He does nothing shameful, corrupt, adulterous, or otherwise embarrassing – nothing constituting “the sorts of bad activities that would cause other people not to want to deal with [him].” Perish the thought. So why isn’t he doing this, or why wouldn’t he?

O artigo de Greenwald é escrito por referência a Richard Posner, mas aplica-se em geral ao argumento "se não tens nada a esconder, qual é o problema da vigilância?".
