The Rule of Law

I rather like the idea of the rule of law.  I fancy living my life unmolested by gangs of thieves and rapists. I also rather enjoy  peacefully exercising my charter rights - unmolested by the government as far as possible.  Last time I checked, charter rights included the freedom of speech and assembly and protecction against unreasonable search and seizure.   http://laws.justice.gc.ca/en/charter/1.html#anchorbo-ga:l_I-gb:s_1

Fundamental Freedoms

2. Everyone has the following fundamental freedoms:
(a) freedom of conscience and religion;
(b) freedom of thought, belief, opinion and expression, including freedom of the press and other media of communication;
(c) freedom of peaceful assembly; and
(d) freedom of association.

I'd say that freedom of expression includes the right to walk around a city without being arrested on the basis of the Bush doctrine.  (You remember W's preemptive strikes, don't you?)  Apparently I'm naive, and Canadians'  rights can be over ridden by secret cabinet decisions.

Questions are piling up about a secret cabinet decision giving police immense power to search and arrest anyone within five metres of the barrier. Legal experts say a regulation authorizing the searches could be vulnerable to attack not just for potentially violating Charter protections against unreasonable search and seizure.  It could also be challenged on the grounds the public was not given adequate notice of the sweeping changes that required them to identify themselves to police officers or agree to be searched.

When did Canada become a police state where basic freedoms can be over ridden in secrcey by politicians? 1997 at the APEC summit? 2010 at the Winter Olympics?
