I can see why Officer 'Bubba-ette' joined in to help subdue the 'perpetrator'. Seeing another cop wrestling with someone on the ground, it was her responsibility to assist the other Barney. In her defense, even if she acknowledged the call was about a 'seizure victim', she would not neccessarily know if the 'perp' was the same victim, so I would give her a 'pass' on jumping into the fray. That said, kneeing him several times was too much, in my opinion.
I guess the moral of the story is, always obey a cop, even if it is physically impossible for you to do so!
