I have a left Ear yet understand the need for my Right
Mr Pott, as much as i congratulate you on referencing a Animated Series in thoughtful discussion (despite it limited application in this context, i believe Britain has had remarkable successes in preventing terrorism through electronic and physical surveillance) and respect your opinion, which you are of course entitled to, i would request you take a more pragmatic view, i may still have my left ear however i am more than capable of understanding that the world is not presented in black and white. You mention how "Liberty is never an acceptable price to pay for Security" and whilst i agree with you in principle i do have a theory to present to you: Suppose the year is 1765 and you live under the rule of an oligarchic state, no doubt you know i am referring to the American Revolution in which through conflict and the implementation of security a nation was formed which is arguably more libertarian than the very state which used to rule it.
Or perhaps you will be more familiar with the events of 1660 in which a Dictator (or "Lord Protector" as he preferred) who had militarized the British state was forgotten as his lineage was cast out of power and a Monarch was crowned in the hope he would restore liberty after decades of military rule.
The point i am making Trevor is that whilst you would prefer Liberty without security the two "cannot exist without one another" as i believe Aristotle said. Now, as is rational should more details arise regarding this my opinions may change, as far as i am aware it has not been announced who was tracked, was it mass surveillance or individuals of interest?
I would also add taht seeing as the headline uses the words "travelers" in this case i would interpret it as saying Canadian Citizens were not the primary target of such a scheme.
