A judge in the state of Washington has sentenced a mother to three months in jail for hitting a convicted sex offender with an aluminum baseball bat.

Before her sentencing yesterday, Tammy Lee Gibson told the judge that laws were needed to keep convicted sexual predators away from children.

The 40-year-old mother of two pleaded guilty to a reduced charge of third-degree assault in January.

Court papers say Gibson saw fliers announcing a sex offender had moved into a trailer park near her home. She went to the man's address, knocked on the door and accused him of molesting her daughters. Even thought Baldwin had not, Gibson hit him with the bat.

She initially was charged with second-degree assault and felony harassment, which could have meant an eight-month jail sentence if she'd been convicted. But the prosecutor and Gibson's lawyer agreed to the three-month sentence.
