I do not believe the car was searched as the incident was going down. That’s just Uncle Chip’s excuse. He claims the cops threw evidence over the door and to the front of the car and to the side of the car... thus tainting items of clothing that were clearly evidence.
They may have looked in the car with their eyes.
Someone MIGHT have popped open the trunk to make sure no kid was inside. It would make sense to do that.
But a full blown search - no.
