That does change things somewhat. While I still think an FU was a childish move on your part I have a problem with private security doing anything that makes others think they are cops. I do wish we could get the whole story from you. I find it hard to believe that he tased and beat you because you said FU.He was a private security guard it turns out, contracted by the city who gave him a police vest. I have many witnesses of the incident who can attest to brutality. Excessive force is a thing regardless if a crime was committed or not (which there wasn't).
