She got a ticket for doing something when she was at a stop light.
It doesn't say she held up traffic, she did not cause an accident.
She applied lip balm while sitting at a stop light.
She broke a law that probably most people would not even know or think of as a crime.
This is a case of police abuse of power. There was no one harmed by her actions, just a cop wanting to be a... powerful. (I would have used other words, but this is a Christian site.)
People can play what if, all they want. What if she held up traffic? What if she crashed into another car? What if...what if...what if...
She applied chapstick and it cost her $200. It harmed no one, nor put anyone in danger. Just a cop reinforcing the abusive nature that people think they have.
