Mandatory Minimums

This undated family photo provided by Lincoln B. Alexander shows, Marissa Alexander in her car in Tampa, Fla. Alexander had never been arrested before she fired a bullet at a wall one day in 2010 to scare off her husband when she felt he was threatening her. Nobody got hurt, but this month a northeast Florida judge was bound by state law to sentence her to 20 years in prison. (AP Photo/Lincoln B. Alexander)
