it happened in the South, and a more primitive and inhuman legal environment you are not going to find anywhere else in the U.S.A.
I have stopped to help people broken down on the side of the road many times in the south, and usually a cop will come along and thank me for helping out.
I made the mistake of stopping to help someone in the northeast once.
A cop stopped, wrote me a ticket for obstructing traffic (because my car was not broken down, and I was stopped in the breakdown lane helping someone else) and drove away, without bothering to help the guy who was broken down.
A judge upheld the ticket, he just waved the fine.
From personal experience, I would say that the south is more humane than the northeast.
