Actually, that is pretty biased.
The Ruling of 'enough 'evidence to pull her over was based on
1) Location (this is a tiny 'locals' road that is apparently used by smugglers because of the lack of border patrol checkpoints)
2) Out of State Plates (again, this road is apparently only used by locals)
3) Her stiff posture and that she sped up after passing the cop going the other way.

The ruling is essentially that 'although these factors when viewed in isolation my be consistent with innocent travel... taken together they may amount to reasonable suspicion'.
Her activity after being pulled over is super shady as well.
