This is absolutely outrageous. Not just because of the piss-poor way they handled it, but also because everyone involved seems to refuse to admit any wrongdoing, going as far as to lie about the situation. The man was “irate”? For the love of god, there is video of the incident.
If you can’t be a decent human being, at least be someone who doesn’t lie about your malice in the face of overwhelming evidence that you did something monstrous.
