DALLAS (October 29, 2009)--Texas Attorney General Greg Abbott has been asked for an opinion on a state law that a Dallas-area woman says allowed her ex-husband to show the couple’s children pornography.

Texas public indecency laws provide certain exceptions for parents and guardians when it comes to the sale, distribution or display of material considered harmful to minors.

KTVT-TV reported that the mother alleges the couple’s three girls were shown images of sex acts on a computer in February while visiting their father in Amarillo.

Two girls, ages 8 and 9, later told a counselor about the incident during a therapy session in Plano.

Their mother contacted Amarillo police, who referred the matter to Randall County District Attorney James Farren in an effort to bring charges against her former spouse.

Farren in mid-September contacted Abbott's office.

Abbott’s spokesman Jerry Strickland said the office is going through the opinions process.
