You realize Snowden didn’t just dump all of these documents on a torrent site right? Given that he’s not a professional journalist and was risking his freedom he grabbed what he could and took it to reputable journalists to do the work of ensuring the leak doesn’t endanger others without a good reason. What else do you expect him to do? If he’d gone to a superior he’d be rotting in jail and we would have no evidence of mass surveillance in this country.
