Fair enough. You might be right. You could say my viewpoint is academic and based on a top down analysis (of mostly store bought books). Yours is more experiential, and based on a bottom up analysis. The problem with top down is that it takes time to make out the details. It's mostly just theory and large assumptions.

I notice you did say that American CN likes a taste of the trafficking trades these days, but they are not locking down the borders. I can agree with that. I used pretty strong language earlier, so strong you'd think each major port of entry had an Italian Jon Roberts operating there. Maybe I went too far because if we are trying to identify the source of a problem, we want to imagine it's every possible hiding place.
