Well, it's not something I consider a huge issue, probably because I'd be apt to do the same thing.

I don't have any more tolerance for a state trooper abusing his power than a governor. But if we ask that the trooper be held accountable, shouldn't we also ask that the governor be held accountable?

What "held accountable" means, you can decide. I'd say in this case the firing of the trooper is appropriate, and in her case maybe a nasty note in her file.
