Story should explain that Wei Huang is the Shanghai police officer that testified against the defendant Shiyuan Shen. G&M, please be clear in your writing.

China is known to torture those charged. With 10 other countries we recently sent China a diplomatic letter against torture. China has a legal secret arrest program, “residential surveillance in a designated location” or RSID,  that allows police to detain someone for up to 6 months in a secret location, without telling the person's family or lawyer.  It will be difficult to deal with legal cases from China while keeping our morals intact.

I can easily see why the CBSA would want to not release all the documents. Such Chinese laws like their RSID program are illegal in Canada and in most of our allies. Criticizm of this illegal program would get China's underwear in a knot, and could start trade sanctions against Canada. Canada needs to be careful with China but still retain our legal philosophy. This is not easy.
