Hong Kong allowed Snowden to leave despite a request by the United States to arrest him, saying documents submitted by the United States did not “fully comply with the legal requirements under Hong Kong law” and it had no legal basis to prevent him leaving. The Hong Kong government also said it wanted more information about alleged U.S. hacking of computer systems in Hong Kong. Over the weekend, the South China Morning Post published new revelations by Snowden about how the United States hacked China’s mobile-phone companies and two universities.
