Nobody is actively trying to catch her out as far as I can see or wage a targeted shaming exercise against her.
What we have is two totally unrelated incidents, filmed by different people which show extreme responses from the same officer (based on what we see from the footage - I appreciate we should always consider there maybe more context we can't view).
You would have thought after the first incident this person might have reflected on how best to de-escalate situations or been offered support/training to do so.
The (over) reaction of this officer in comparison with their colleagues is very, very stark. The use of pepper spray, rushing at people, chasing after those already moving back to highly agitated body language and yelling was in significant contrast to her peers.
The reason this second film has gained traction is not because she is in it, but because of the behaviour she displayed which has echo's of previous recorded "form" for inflaming situations.
Had she behaved like the other officers, this second film wouldn't have gained any traction at all.
