On what grounds would the police have stopped them?

What were they arrested for at the bus station? Kidnapping?

The police stopped them because of the reported sighting of the man they were looking for in connection with the Smart case. Then, lo and behold, there was Elizabeth, too.

No. They weren't "arrested." They were wanted for questioning, and they got two separate calles from people who claim they had seen the guy on the photograph.

The cop stopped him because of those reports.

There is a difference between "being arrested" and being taken in for questioning.
