You think this is a movie? You don't rush towards terrorism you run away from it. When people are willing to use violence you get away from them you don't engage them. Yes the authorities absolutely need to investigate what happened and who made the threats and deal with them accordingly. But no the people of Calgary should not be willing to throw themselves into the line of fire like lemmings simply to "combat terrorism". When there is a threat you avoid it, you don't challenge it. The authorities made the right call here, and for you to question it is innane and only shows your lack of life experience. Grow up, we're not living in a Harrison Ford movie.
