There is a good reason I keep in my ignore list trolls who read one thing ("if you ask me about US Border patrol I have to mention that..." , "having crossed the US border many times, and having seen hundreds, may be thousands of others cross through POE in front of me....", with no mention of number of times Canadian border was crossed) , and then see into it something that isn't there (such as: "if you ask me about Canadian Border patrol I have to mention that..." , "having crossed the Canadian border many times, and having seen hundreds, may be thousands of others cross through POE in front of me....".
Hard to parse this but let's be clear: the original claim was "if you ask me about US Border patrol I have to mention that it will not treat you the same way Canadian will ... I can say that I haven't seen same behavior/attitude in US border patrol as I have in Canadian". This is, of necessity, a claim of comparison between two border services.
From an individual who (clear from the posted link) has not crossed the Canadian border in, at minimum, several years, and possibly not that much at all.
But by all means: if this 'expert' wishes to clarify the extent of experience, fine. The record of inaccurate statements is clear, however.
