I think they should talk to the Mexican government about this. They might have some interesting insights into the issue. PS: On second thought, I think it's a great idea. Let's see what the Canadians think of warrantless midnight home invasions at the wrong address with pets shot and family members obliged to stand around half naked in the yard while a squad of apes tosses the entire premises. It should be fun, and I don't think it will be swept under the carpet the way it is in the U.S.
This should tell every Canadian that they are now a fully vassal state to the US. No sovereign state should let someone elses' police force operate like this. What's next, inserting US judiciary inside Canada?
