Four men, facing trial for subversion, cowered before a court where they were represented by lawyers they didn't choose.

A fifth person, knowing her husband was detained and teenage son under surveillance, declared her wrongs in a videotaped interview.

China is in the midst of what many overseas scholars say is its harshest crackdown on human rights and civil society in decades. Since Xi Jinping came came to power nearly four years ago, hundreds of activists, lawyers, writers, publishers and employees of nongovernmental groups have been rounded up. Many more have been threatened and intimidated. Internet news sites have been ordered to stop publishing reports from sources that aren't sanctioned by the state.

Even as China has been touting its efforts to boost the "rule of law," some critics of the government have vanished under mysterious circumstances in places like Thailand and Hong Kong, only to surface months later in Chinese custody, claiming rather unbelievably they had turned themselves in voluntarily. Many of those detained have appeared on state-run TV confessing to crimes before they have had a day in court.
