Rick, if there is a certainty of the perp being in 1 of 19 cars within a narrow geographic area and all they need to do is sort it out, why then is this a problem?

You are correct that anyone could have stepped away from their car locking it behind them. They have that right. In this circumstance, the police will tow the car to a compound and await a warrant. Ask me how I know.

So, you might as well consent if you have nothing to hide and be on your way.

2 hours does seem like a long time, though. I wonder what the explanation for that is.
