This is why at a Border Patrol checkpoint the dog is right there on primary. More later if anyone is interested I am pressed for time right now.

I would be interested in understanding a few things about the dog.
1. Is the dog trained to detect the presence of a human or just the odor of a human? In other words, If I had let a hitchhiker out 5 miles back would the dog alert the the residual odor?
2. If the dog is trained to alert to either the odor or actual presence of a human why does it not alert on every car? It seems to me that pretty much 100% of cars at the checkpoint will be driven by a human?
3. Is the dog trained to differentiate between humans "in plain sight" and those not visible?
4. Do humans in the US legally have a distinctive odor different from those here illegally? In other words, how does the dog determine the immigration status of those humans it smells?
