"Border guards protect us from all kinds of criminal behaviour."
They do? The conversation I had on my last crossing into Canada, verbatim:
Border agent: "Where are you going"?
I replied with one word
Border agent: "How long are you staying"?
I replied with two words
Border agent: "Have a nice day".
The whole conversation took 20 seconds.
I'm sure you feel much safer. I know I sure would if I were you.
