A Hong Kong court Thursday convicted 14 pro-democracy activists in the city’s biggest national security case under a law imposed by Beijing that has all but wiped out public dissent. Those found guilty included former lawmakers Leung Kwok-hung, Lam Cheuk-ting, Helena Wong and Raymond Chan. They could face up to life in prison when sentenced later. The two defendants acquitted were former district councillors Lee Yue-shun and Lawrence Lau.
