Actually, you are misguided there. 1st off, it wasn't the carnival that told him to stop, it was the johnny cops of Chicago.
2nd off, they let him in the gate with the dSLR and tripod. 3rd, we aren't talking about going onto private property that isn't open to the public. For example if a coffee shop asked me not to take a pic, I would take it under consideration, but if the got nasty, I would make an effort to
advertise for them. What I am getting here is that private property that is open to the public doesn't automatically make people surrender their rights. Personally, I wouldn't have just got the cops badge number, I would have got his portrait and sent it to the local papers etc, and I would have done it in a nice way and give him my business card which isn't a photographer. Given iPhones etc, the whole idea is idiotic but then again we are talking about the Chicago PD.
Edit: I just realize you are in Australia so maybe cafe owners can bully folks.
Here we have a term called, "going out of business."
