Lucius Malfoy should have been arrested for threatening the school governors. There was plenty of overt evidence for that!

Why didn't he get arrested based on Harry, Dobbys potential testmonies that he was behind the opening of the chamber of Secrets?? The first acusation could also be used as evidence
