Crystal Buckner responds to a reporters question Thursday in Dallas. Buckner is fighting to have a 1970s-era Texas law that allows parents to show "harmful material" to their children. A prosecutor said he couldn't file charges against Buckner's former husband, who is accused of forcing his 8- and 9-year-old daughters to watch hardcore online pornography. (AP Photo/Amy Gutierrez)
