The CCTV footage shown at the domestic abuse trial was disturbing: The defendant is seen dragging his wife by her hair, and then punching and kicking her. The trial of businessman Kuandyk Bishimbayev, Kazakhstan's former economy minister, in the death of his wife, Saltanat Nukenova, has touched a nerve in the Central Asian country. Tens of thousands of people have signed petitions calling for harsher penalties for domestic violence.
