The article says they did have an authorization letter from the state court officials (the people running the building) and they were released right after the letter was verified with the court officials.

At least from what I can see, the police officers involved were doing the right thing. They detained the suspects, made a proper effort to listen to them and validate their story, and then released them.

It was the Sheriff who showed up and didn't like it who then hassled them further.

They basically had a no-objection letter from the people in charge of the building and the police officers were onboard. It was one person who tried to turn it into something else.
