Describe a scenario in which an individual is detained and interrogated by a US agent in Toronto, and express dissatisfaction with the new law in this situation.
So one speaks to the US agent in Toronto, says "oh damn, I forgot my passport", and the agent is suspicious. He detains you until they can establish your identity. They interrogate you. And, when they don't like what you are saying, or you show a bit too much heat from all the questioning, they arrest you.  Ok, got it, thats the new law. It sucks.
