Activist artist Ai Weiwei speaks to journalists gathered outside his home in Beijing, China, Thursday, June 23, 2011. Ai, the most high-profile target of a sweeping crackdown on activists in China, has returned home late Wednesday after nearly three months in detention. The official Xinhua News Agency said Ai confessed to tax evasion, accusations his family had long denied and which activists had denounced as a false premise for detaining him.
