UNIVERSAL STUDIOS CITYWALK NIGHT CLUBS in ORLANDO

I had a horrible experience at Unviersal Studios Orlando on the July 4th weekend... These people know how to ruin a vacation. I was kicked out of a club called Groove for wearing a black hat. What surprised me is that a lot of people in there were wearing hats. Me & my sister were asked to leave so we did not happily but we did without fighting. We were walking out of the city walk when my sister realized that she forgot some merchandise at the club. We turned around and we were being followed by a few security memebers & 2 police officers. This was a surprise being that we were leaving without any problems. We turned around and the police officer slapped our drinks out of our hands and proceeded to arrest me. He did not saying anything but that I was under arrest. This baffled me. He did not read me my rights or tell me why I was being arrested. Once they got my another location, they proceed to laugh and carry on like this was a joke, they filled out the reports and it did not indicate what really happened. I was of course upset, but did not know what to do. I was then taken to jail, inwhich I was bailed out. What I don't understand is why all this happened the way it did. We were leaving the property, but even though we were kicked out for a hat, why was it such a big deal. I did not get into a fight or anything of that nature. What happen to my rights? Universal Studios needs to rethink their security and police officers on property. I don't know what to do about this and I'm scared to go back to Florida due to the Police force there. They were very rude and acted like this was a joke to them. So if you are thinking of hanging out at CITY WALK @ Universal Studios ORLANDO, be careful of what you wear and stay on your P's & Q's because the security & police there are not kind, I think they are looking for something to do or someone to arrest.
