This is not passing the smell test.
It’s almost looking like she was trying to set up a confrontation?
Well, if she was, the cop most certainly (and unprofessionally) obliged her.
IMHO, the escalation began when the cop ordered her out of the car. Evidently, in Texas a cop has the right to issue that order. But I see no reason for that order, none at all. The cop chose to escalate the situation. It's on him.
