“My position with Booz Allen Hamilton granted me access to lists of machines all over the world the NSA hacked,” he told the Post on June 12. “That is why I accepted that position about three months ago.”
Snowden also showed the paper information "that he claimed showed hacking by the NSA into computers in Hong Kong and mainland China."
“I did not release them earlier because I don’t want to simply dump huge amounts of documents without regard to their content,” he said.
“I have to screen everything before releasing it to journalists.”
Asked if he specifically went to Booz Allen Hamilton to gather evidence of surveillance, he replied: “Correct on Booz.”
His intention was to collect information about the NSA hacking into “the whole world” and “not specifically Hong Kong and China”.
