I'm curious why and how the city would give a security guard a vest that says "Police" on it?! That's simply plain stupid. I'd be more inclined to believe that the security guard got the vest himself.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).
Where were you that a security guard contracted by the city - at a private venue - would be interacting with you?
If the police are investigating, are they pursuing the matter as a battery against you?
