fugitives in the library

In my dream a family (husband, wife and adult daughter) were fugitives- it seemed like for a noble reason in my dream but I don't know what it was. There was a heavy police presence (maybe even SWAT) in the library while the people were looking for material. They weren't handcuffed or bound just the police were watching them. In spite of this, the daughter gave them the slip when they went downstairs to see someone at the front counter. The parents were happy that there was freedom.
