By Niya Kenny's standards, Oct. 26, 2015, began as a normal morning. She walked into her school, Spring Valley High, a little late. But it was a Monday.
A few hours later, she'd be escorted out in handcuffs.
Her day began with algebra class. She parked herself at a desk near an electrical outlet up front — not her usual seat. Kenny was 18 and a senior at the school near Columbia, S.C.
She saw her teacher having a hushed conversation with a student a couple years younger than her.
