I remember this written about Aziz by Christopher Hitchens (has always stayed with me):
"The son of deputy prime minister Tariq Aziz was sentenced to 22 years of imprisonment last year; he has since been released and rearrested and released again, partly no doubt to show who is in charge.... Saddam Hussein likes to use as envoys the men he has morally destroyed; men who are sick with fear and humiliation, and whose families are hostages."
