Citizens may argue with officers. Unless you were an eyewitness, you have no proof that Bumpas ignored any commands of the armed officers. The only bullying that there is concrete proof of was Officer Sharlow's, when he attacked a hand-cuffed Bumpas. People being arrested are not always "respectful" because oftentimes they disagree with the reason and conditions of their arrest. The law says nothing of "respect" but does provide rules for both citizens and officers where violence is concerned. Sharlow violated the law and will pay the penalty. The fact that he engaged in this criminality on camera is likely a demonstration of the degree to which officers believe themselves to be immune to prosecution for crimes against those they arrest.
