Start from the SFist story:
"...Arnie's office announced that they had proof that somebody had broken into the computer system. They suspected someone from the Angelides camp and had proof to back it up. After some hemming and hawing, the Angelides people finally fessed up."
Well, no; what the Angelides people fessed up to is finding audio files on the governor's website. Audio files which nobody had directed them to, sure, but - they were there, and easily available to anybody with a good idea of how web browsers work.
Says the San Francisco Chronicle:
"Calfo said a campaign staff member assigned to monitor Schwarzenegger press releases followed a link provided by a memo from the governor's office on Aug. 29 to an audio tape of a speech on the anniversary of Hurricane Katrina.
"But, by editing the link's Web address just slightly, the researcher was able to access a directory of other audio tapes that included those of private meetings, including the one that later was leaked to the Times."
Editing web addresses is common practice for advanced web users; taking the step (making one setting in a configuration file somewhere) to keep web users from browsing directories you don't want them to see is common practice, too. Browsing through an audio directory on a website is like hitting zero to reach an operator when you're trying to navigate a voicemail system, despite the system not telling you you can do so; or hitting a well-known sequence to get a company directory on that voicemail system even though the system doesn't tell you you can do it.
Strange that anyone aside from the Schwarzenegger campaign is getting flak for this. Strange that anyone thinks Arnold's not the type to make these types of comments, too; I'd think those who voted for him and those who voted against him expect this from him. He doesn't market himself as a sensitive guy.
