So just thugs with a government issued badge.
The point of the post was there ARE people impersonating officers. They had stolen uniforms.
Perhaps Tyre didn’t know those that pulled him over were real cops. From what we hear they didn’t have uniforms. So he might have thought they were pulling off the same crime as had been in the news, acting like you’re a cop but you’re not.
But in the end that doesn’t matter. They had no right to beat and kick him like they did.
