It's Only A Security Breach If You're An Authoritarian

We all know that Harper does his level best to stage-manage every aspect of a public appearance.

Civil protest - like this - is not a "security breach" - it is a protest.  Only authoritarians are going to call it a "security breach".

Think about it ... what is Harper afraid of that he has to have lines of security that dense?  It's not exactly like Canada has a history of violence against Prime Ministers - no matter how bad they may be.
