Aaron Swartz, a coder, activist, and former ethics fellow at Harvard University, was arrested and charged with hacking for downloading a large quantity of academic articles from JSTOR and evading attempts to be removed from the network, reports Ryan Singel at Wired. Singel adds that Swartz "has a history of downloading massive data sets, both to use in research and to release public domain documents from behind paywalls." Swartz allegedly stole 4.8 million articles and broke into a computer wiring closet at MIT, the Associated Press says. Swartz pled not guilty to the charges. Wired adds that the documents have been returned to JSTOR.
