The union that represents police officers in Los Angeles has filed a law suit against LA Police Department Chief Charlie Beck.

The union claims he's violated the due process rights of officers by pressuring the department's three-person disciplinary panel to dole out certain punishments, like firing them...

The union says officers who do not deserve it are being dismissed, but the group has yet to present concrete example of this, citing privacy, according to Southern California Public Radio reporter Frank Stoltze.

Stoltze talks with A Martinez about what's at the root of the lawsuit and the history of tensions between the police union and Chief Beck.
