No. But I was respectful and treated the US Marshall like I would a police office if he was merely asking questions. In the article, the person involved was uncooperative from the beginning and that only made matters worse.

How was he uncooperative? Refusing to let an officer search your belongings (politely) is not being uncooperative.
