This is a simple case of an egotistical politician who wishes he was King tussling with the media that is rightfully making him look incompetent. "Anyone who disagrees with me is a criminal" is a common pattern for wannabe dictators. Vote against him at the next opportunity.
It would be better if the SSNs were white text on a white background and we were here because someone highlighted the text, though.
No. The reporter did the equivalent of opening a book available to be read by the public and having the audacity to try and figure out what the words on the pages meant.
The reporter asked for a page of information, it contained information that wasn't supposed to be there, and he's being blamed as if his eyes manifested it into existence.
Seems more akin to shining a UV light on a piece of paper. (Interesting how the sibling comment came to a similar example with invisible ink.)
It's still not a perfect metaphor. It's not immediately clear that 1) is true here (the reporter probably was not trolling for private information) and it's highly questionable if 2) is true as it seems that this info was being sent along in HTTP responses. What is obvious to me is that that this guy had no malicious intent, took steps to do responsible disclosure (they didn't publish the article until the issue was fixed) and is being targeted by the political establishment as retribution for embarrassing them. Shameful stuff.
All analogies aside, intent matters, and the reporters intent was to report a vulnerability and then to report the Government's actions to the public once the vulnerability was fixed. Neither of which are illegal.
The onus is on the person providing the information to not include it in what they provide, not the viewer to not look at information provided.
A better analogy would be that the state sent the journalist a document with everything readable in regular light, and a separate sheet that tells him which words he must redact. There was no attempt to conceal information, and worse, the redaction list would have been promptly ignored by anyone using a screen reader or other accessibility devices.
What's actually happening is: someone is broadcasting the data. End of story.
Now I'm going to ignore my own advice: it's like displaying the data on a big screen in the town square and then trying to arrest people for turning their head to look at it.
Then a reporter came along and rubbed a pencil on it, revealing the writing from the sheet above it.
The reporter did the equivalent of noticing a lock was rusted through and barely hanging on. He poked the lock and it crumbled to pieces. He didn't take anything, he reported the problem to the government and later to the public. He didn't take the personal data just because his eyes saw it in passing.
If the reporter compiled a database of every teachers personal information, that's another thing. That's not what happened, the reporter looked at 3 teachers to establish the pattern and then reported it.
