He knows a thing or two about law enforcement, the judicial process and essential liberties. All that has Conrad Black incensed at Bill C-51 which he sees as a threat to the freedom of the Canadian people. He doesn't like the place into which he believes Stephen Harper plans to lead the country.
...We have ample proof, from the McDonald Commission’s 1981 report and elsewhere, that the law enforcement agencies in this country, as in others, are capable of outrageous and unfathomably stupid abuses, and anyone who has had anything to do with any arm of the law knows it (although most people in these occupations are reasonably dedicated and honest). Definitions have to be tightened; oversight has to be stringent and prompt and answerable to parliament, and we should be careful of too much reciprocity with foreign governments. Only 10 or 12 other countries have as much respect for human liberties as Canada does and must retain; the United States, with its 99.5% conviction rate and stacked rules — a criminal justice system that is just a conveyer-belt to its bloated and corrupt prison industry — is not one of them. If we go to sleep in Canada, we will wake up in an unrecognizable despotism, like Argentina, Turkey, or Louisiana.
