Well, as she had explained, they first interacted with her because her daughter was using Wheelies down a hill, which isn't allowed in the park (for liability reasons).

Then, I imagine, the officer that made contact with her told her that her shorts were too short and she needed to change, which led to her ignoring the police (due to her autism, according to the lady with the shorts), which then led to her trespass citation.

I don't think it was a legitimate reason but I also do not manage the park's rules. It is technically private property and if they don't want people in there with short shorts, that is their prerogative, though I imagine they don't enforce those rules equally.

I personally don't think it was right to ask her to change. I didn't see anything wrong with the shorts, but again, I don't manage the park and I don't make the rules.

And another issue I have with the situation is that they let her into the park wearing those clothes and she was allowed to walk around for some time before that happened.

So, they probably need to have very specific rules that are visible at the park entrance, and dress code should be checked at the gate and at all entrances to rides.

Otherwise, they'll end up giving society the opportunity to believe they are being unfair, which I do believe they were - for whatever reason. Maybe the female officer was jealous - who knows.
