It was not trespassing to hand out material on private property.
Basically the whole area was a privately owned town. It was a company town, kind of like Facebook, google and twitter. Sure they say they are private but they HAVE the public square and can not diminish others rights of assembly or speech.
This is exactly what they are doing. One can try and squirm all they want into the subject but those entities own the public square and they can not step on your rights. They need to be sued.
Sure it is their town and they can run it how they like but they need to continue with the principles within our society, laid down n our founding documents.
