Umm, the DA dropped all charges against the woman, said there was absolutely no grounds for her arrest... read the whole story.
I did not say the officer did act appropriately. I also am not saying that he didn't. There IS missing facts in this situation, and also an apparent disconnect among those who missed the part in the video where the woman was too close to the police when she was initially confronted. YOU might wish to rewatch the video, and pay close attention to the officer's comment to this woman where he states she is on the sidewalk (not in her front yard), at which time the woman begins backing up (clearly observable if you pay attention to the video). Police, properly trained, will require bystanders to not be in close proximity to a police action, and rightly so. Simply because the DA did not wish to pursue charges is not evidence that the officer acted wrongly. Also missing is any video evidence of just what comments the woman made prior to the video starting (something the officer also alludes to). If she made comments which prompted the officer to address them, perhaps that could explain his reaction. There is a few missing elements IMO.
