OK....
Had that person been a minority, we all know what would have happened.
This action by this police officer was utterly unwarranted. I (as has been said) would not have pulled over there either.
Reminds me of a personal story involving my college roommate. Got out of college, went to work for a Senator in DC. A couple years out of college, he goes out one night, drinks a few too many, stupidly decides to drive home on the D.C. beltway. Gets pulled over by a black female state trooper. On a shoulder almost exactly like this. He gets arrested, goes to jail, had to have dad come bail him out.
Mandatory court date comes, he goes to court with his dad. Eventually they call his case, he approaches the bench. Immediately the judge says to him something to the effect of "Sir, without the officer present, and without witness to your crime, there can be no crime against you. All charges are dropped." The state trooper wasn't there. Dumbfounded but relieved, he leaves court.
But he's bent on figuring out why she didn't show up. LEOs don't miss court for serious offenses like DUIs.
This is the early 90s, weak internet available but he eventually finds out that she had been involved in another traffic stop on the beltway. As she was standing at the drivers window of that car she pulled over, she was clipped by a passing car and killed on the spot.
He said it shook him hard (good) and he never got behind the wheel again after drinking because of this (good). Great learning experience for him.
Point is...those shoulders with a concrete barrier are the worst places you can pull over and every cop knows this. Why he insisted she pull over there and pulled that maneuver is reckless and should cause outrage.
