I was stationed at Pearl Harbor fairly far back in the previous century. There was a group of protesters just outside one of the gates, doing nothing but handing out copies of the Constitution to people leaving the base.

They were arrested for trespassing, as they were standing on usgov property. But they were really arrested because they were making trouble.

No, I don't remember their affiliation or what they were trying to accomplish. Maybe they actually were just troublemakers, which has never been against the law but which will always attract a smackdown.
