WATERLOO, Canada — Australian businessman Stern Hu has been convicted of taking bribes and stealing state secrets and sentenced to 10 years jail in China. International standards of a free and fair trial do not seem to have been met.

Did the Rudd government do all within its powers to help him? Did the Howard government do enough, and early enough, to help Australian citizen David Hicks who was caught up in the nightmare of Guantanamo?

Canadians too have been caught up in nightmarish situations overseas — from being trapped in Lebanon during the 2006 war to being renditioned to Syria, sent to Guantanamo, imprisoned in Mexico and detained in Kenya.
