american border agents have to be among the stupidest people on the planet.
Part of the reason this guy got so much hassles besides the fact he was also being a bit of a dick is that border agents with canada are told not to turn back canadians because over the years they have gotten attention for being rude and abusive to tourists when canadian border agents don't treat american tourists that way.
So they arent really allowed to turn back mouthy rude canadians UNLESS they break the law , so they goad them into being confrontational so they can turn them back.
I travel across the border alot so i have run into some really funny ones myself, been "semi-arrested" at least a half dozen times.
I have multiple citizenships ( 4 ) so i like to toss them a curveball when i go across. I always cross into america showing my canadian citezenship, then when they start asking the questions i be really vague.
me - " gonna go get me some guns and ammo "
agent - "what did you say"
me - "guns n ammo son, i likes to shoot"
agent - "what is the purpose of your trip business or pleasure "
me - " little bit of both, if i am lucky, do you know any hot escorts "
agent - " you had better cooperate or you will not be crossing the border today "
me - "i forgot to mention i am an american with diplomatic ties
"
agent - types on computer for a bit " have a nice day "
