Here is another article dealing with China's poor criminal justice system. These quotes are particularly troubling:
"China executes people for 68 offenses, many nonviolent, including smuggling, tax evasion, corruption, "endangering national security" and separatism, which includes advocating Tibetan or Taiwanese independence;"
"In a recent reform, China introduced a national law exam for judges and imposed a 12-hour limit on police interrogation, down from 36 hours;" and
"In the late 1990s, China pioneered the use of mobile lethal-injection vans. Reports suggest their use is particularly common during anti-drug campaigns in the southern province of Yunnan. "
