So, if I read this aright, you are of the opinion that the training police receive to secure an area in which a police action is taking place should be thrown out. That a citizen who is within feet of a police action should be completely ignored? How many LEO's are you willing to see killed by this new expectation? Or, are you expecting LEO's to be mind readers and know who poses a threat and who does not? Would you feel comfortable as an LEO with someone standing within feet of you and/or your fellow officers while engaged in a police action? Can you even place yourself in those shoes? Are you even willing to try? It is not I who have allowed logic or judgment to lapse here.
Let's keep the discussion to the facts of this case, not your hypothetical. When you watch the video you will note it BEGINS with the suspect in handcuffs. When you watch the video you will note of the cops IN FEAR at least one remains with his back to camera. You will also note that the bad cop has to walk many feet to get to GOOD. You will note there are other people accompanying Good (camera does not levitate and continue filming on own)
