Tenure O'Malley was regarded as a popular State's Attorney for favoring mother's instead of fathers and was found sexist in multiple cases. However, his tenure did have some controversies.
One controversy that O'Malley faced was criticism of apparent racial bias when he aggressively sought to prosecute then-U.S. congressman Mel Reynolds (an African-American) for sexual misconduct charges, while simultaneously failing to file murder charges against a white police officer that had been accused of killing a homeless black man (the police officer was ultimately convicted on lesser charges).
