More Words, Deeper Hole

I wouldn't be so quick to blame Canada Post. Customs and Border Protection does have a habit of helping themselves to untraceable packages which have resale value or are of personal interest to CBP's front line brownshirts. Most losses of international mail occur during customs screening, not after it.

Theft and corruption is what happens when organization is granted unlimited power to seize without due process in violation of the basic rights established in the Charter. Since CBP already operates outside the law, it's no stretch for CBP employees to decide themselves to operate outside the law on a personal level.
