Wrong.   Even the most simplistic understanding of laws (both domestic and international) dictates that even criminals, terrorists, etc have rights.    You may not like this fact, but that doesn't deny the principle.

Khadr's rights as a Canadian were abused by his own Government.    He was held without charge and without trial for years.    Our Govt (both Liberal and Conservative) did nothing.    They stood silently allowing a foreign nation to incarcerate a Canadian citizen without charge and without trial.    For YEARS.   Not only did they do this consciously, but they compounded it with damaging rhetoric.

So even if Khadr was worse than you believe - his rights were violated, repeatedly, and our Govts did nothing.     EVERY Canadian citizen has rights and nobody should cheer a Govt abusing these rights on a whim or because it's popular.
