The Communist Party cracks down on political activists, even as it eases up on some less sensitive legal cases

A human-rights lawyer and three activists have been found guilty of “subverting state power” in a series of trials in the northern city of Tianjin. With resonances of the show trials of China’s Cultural Revolution in the 1960s, they are the latest part of a crackdown on Western ideas and social and political activism that began in earnest after Xi Jinping became Communist Party chief in 2012.
