Lots of schools are using iPads and other gizmos in the classroom, but now a few downsides are surfacing. Widespread hacking might be expected, but teacher assault by a 9-year-old? The Smoking Gun reports that police in Rock Hill, South Carolina, were summoned when a boy erupted into a rage after his 26-year-old female teacher confiscated his iPad in class. After he started to flip chairs, the teacher escorted him into the hallway, where he proceeded to repeatedly stomp her foot, leaving it bruised and swollen. It took four adults to restrain the youth, notes the State. Police released him into the custody of his mother instead of arresting him.
