Well, for starters, the cop KNEW there was a pregnant woman being delivered to the hospital. He was advised by dispatch as much...since he threatened the man with these exact words:
"You will be in jail tonight, and you will not be there when your child is born"
So, for me, what takes me "through the roof" in this situation is that the cop is more concerned with his "authoritah" than the actual well-being of those people he is sworn to serve.
From the (admittedly limited) contents of this video, it seems like the police knew the totality of the situation before they endangered the lives of a pregnant woman and her child.
A medical emergency always trumps a traffic infraction...no?
I think the answer is, "it depends." ....well, if its solely an infraction, I guess yes. But if the driver is reckless, I'd say not. I certainly would pull over a car, that I knew contained a woman in labor, if the driver of the vehicle was endangering the public. You just have to weigh the totality of the circumstances.
And I'm not 100% confident that a woman in labor qualifies as a medical emergency.
