According to the article, trespassing. Trespassing is illegal. The article makes no mention of "a public employee not liking you" as being a crime so I'm not sure why you keep bringing that up.

Why are you focusing on the citizen when I asked you about what crime the officer committed? You claim kidnapping, now provide a legal argument as to why what occurred was kidnapping instead of simply arresting, which is something the police have the legal power to do.

Also, how does this make all police in the city dirty?

Lastly, if you truly feel that a crime was being committed, why are you here on reddit instead of executing a citizen's arrest?
