"There really is no time to think about this... just send in the money"

More "fun" at borders INSIDE the US. I was wondering when this would happen.

I present these for consideration. My understanding is that an officer can Detain you for any reason while he determines if a crime has been commited. You don't have to answer questions or allow yourself to be searched, but you can't take off. Is this true? If so, then this is why this guy couldn't just drive off.
